[svn-r13744] Description:
Initial changes to take advantage of readers/writer locking on metadata cache entries. Reduce the # of protect/unprotect pairs during B-tree iteration by holding reader lock on B-tree and symbol table nodes while iteration occurs. This also has the benefit of preventing an iteration callback from modifying the B-tree being iterated over (which would probably confuse the B-tree iteration code terribly) Tested on: Mac OS X/32 10.4.9 (amazon) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
