Sears Russell	c7fa929e71	This fixes in Stasis issue 22. ... Replacement policies now track the pin count of each page that they interact with. This behavior used to live in bufferHash, and had never been ported to concurrentBufferManager. For various reasons, the pin counts have to be updated atomically with the LRU state. This would be very difficult to do inside of concurrentBufferManager, which sometimes needs to add and remove pages to replacement policies without holding any other latches.	2010-04-20 01:09:32 +00:00
