-/* ParseFTPList() parses lines from an FTP LIST command.
-**
-** Written July 2002 by Cyrus Patel <cyp@fb14.uni-mainz.de>
-** with acknowledgements to squid, lynx, wget and ftpmirror.
-**
-** Arguments:
-**   'line':       line of FTP data connection output. The line is assumed
-**                 to end at the first '\0' or '\n' or '\r\n'. 
-**   'state':      a structure used internally to track state between 
-**                 lines. Needs to be bzero()'d at LIST begin.
-**   'result':     where ParseFTPList will store the results of the parse
-**                 if 'line' is not a comment and is not junk.
-**
-** Returns one of the following:
-**    'd' - LIST line is a directory entry ('result' is valid)
-**    'f' - LIST line is a file's entry ('result' is valid)
-**    'l' - LIST line is a symlink's entry ('result' is valid)
-**    '?' - LIST line is junk. (cwd, non-file/dir/link, etc)
-**    '"' - its not a LIST line (its a "comment")
-**
-** It may be advisable to let the end-user see "comments" (particularly when 
-** the listing results in ONLY such lines) because such a listing may be:
-** - an unknown LIST format (NLST or "custom" format for example)
-** - an error msg (EPERM,ENOENT,ENFILE,EMFILE,ENOTDIR,ENOTBLK,EEXDEV etc).
-** - an empty directory and the 'comment' is a "total 0" line or similar.
-**   (warning: a "total 0" can also mean the total size is unknown).
-**
-** ParseFTPList() supports all known FTP LISTing formats:
-** - '/bin/ls -l' and all variants (including Hellsoft FTP for NetWare); 
-** - EPLF (Easily Parsable List Format); 
-** - Windows NT's default "DOS-dirstyle";
-** - OS/2 basic server format LIST format;  
-** - VMS (MultiNet, UCX, and CMU) LIST format (including multi-line format);
-** - IBM VM/CMS, VM/ESA LIST format (two known variants);  
-** - SuperTCP FTP Server for Win16 LIST format;  
-** - NetManage Chameleon (NEWT) for Win16 LIST format;  
-** - '/bin/dls' (two known variants, plus multi-line) LIST format;
-** If there are others, then I'd like to hear about them (send me a sample).
-**
-** NLSTings are not supported explicitely because they cannot be machine 
-** parsed consistantly: NLSTings do not have unique characteristics - even 
-** the assumption that there won't be whitespace on the line does not hold
-** because some nlistings have more than one filename per line and/or
-** may have filenames that have spaces in them. Moreover, distinguishing
-** between an error message and an NLST line would require ParseList() to
-** recognize all the possible strerror() messages in the world.

- There is a race condition between the layout and load completion that affects restoring the scroll position.

- 1) If first layout happens before the load completes, we want to restore the scroll position then so that the
- first time we draw the page is already scrolled to the right place, instead of starting at the top and later
- jumping down.  It is possible that the old scroll position is past the part of the doc laid out so far, in
- which case the restore silent fails and we will fix it in when we try to restore on doc completion.
- 2) If the layout happens after the load completes, the attempt to restore at load completion time silently
- fails.  We then successfully restore it when the layout happens.

-// This cache holds subresources used by Web pages: images, scripts, stylesheets, etc.
-
-// The cache keeps a flexible but bounded window of dead resources that grows/shrinks 
-// depending on the live resource load. Here's an example of cache growth over time,
-// with a min dead resource capacity of 25% and a max dead resource capacity of 50%:
-
-//        |-----|                              Dead: -
-//        |----------|                         Live: +
-//      --|----------|                         Cache boundary: | (objects outside this mark have been evicted)
-//      --|----------++++++++++|
-// -------|-----+++++++++++++++|
-// -------|-----+++++++++++++++|+++++
-
-// The behavior of the cache changes in the following way if shouldMakeResourcePurgeableOnEviction
-// returns true.
-//
-// 1. Dead resources in the cache are kept in non-purgeable memory.
-// 2. When we prune dead resources, instead of freeing them, we mark their memory as purgeable and
-//    keep the resources until the kernel reclaims the purgeable memory.
-//
-// By leaving the in-cache dead resources in dirty resident memory, we decrease the likelihood of
-// the kernel claiming that memory and forcing us to refetch the resource (for example when a user
-// presses back).
-//
-// And by having an unbounded number of resource objects using purgeable memory, we can use as much
-// memory as is available on the machine. The trade-off here is that the CachedResource object (and
-// its member variables) are allocated in non-purgeable TC-malloc'd memory so we would see slightly
-// more memory use due to this.
