Revert r73790, and replace it with a significantly less ugly solution. Rather than trying to make the global reader-writer lock work,
create separate recursive mutexes for each value map. The recursive-ness fixes the double-acquiring issue, which having one per ValueMap
lets us continue to maintain some concurrency.
