-// Existing versions of the Flip4Mac WebKit plug-in have an object lifetime bug related to an NSAlert that is
-// used to notify the user about updates to the plug-in. This bug can result in Safari crashing if the page
-// containing the plug-in navigates while the alert is displayed (<rdar://problem/7313430>).
-//
-// The gist of the bug is thus: Flip4Mac sets an instance of the TSUpdateCheck class as the modal delegate of the
-// NSAlert instance. This TSUpdateCheck instance itself has a delegate. The delegate is set to the WmvPlugin
-// instance which is the NSView subclass that is exposed to WebKit as the plug-in view. Since this relationship
-// is that of delegates the TSUpdateCheck does not retain the WmvPlugin. This leads to a bug if the WmvPlugin
-// instance is destroyed before the TSUpdateCheck instance as the TSUpdateCheck instance will be left with a
-// pointer to a stale object. This will happen if a page containing the Flip4Mac plug-in triggers a navigation
-// while the update sheet is visible as the WmvPlugin instance is removed from the view hierarchy and there are
-// no other references to keep the object alive.
-//
-// We work around this bug by patching the following two messages:
-//
-// 1) -[NSAlert beginSheetModalForWindow:modalDelegate:didEndSelector:contextInfo:]
-// 2) -[TSUpdateCheck alertDidEnd:returnCode:contextInfo:]
-//
-// Our override of 1) detects whether it is Flip4Mac's update sheet triggering the alert by checking whether the
-// modal delegate is an instance of TSUpdateCheck. If it is, it retains the modal delegate's delegate.
-//
-// Our override of 2) then autoreleases the delegate, balancing the retain we added in 1).
-//
-// These two overrides have the effect of ensuring that the WmvPlugin instance will always outlive the TSUpdateCheck
-// instance, preventing the TSUpdateCheck instance from accessing a stale delegate pointer and crashing the application.
