Quincey Koziol 670d598ff7 [svn-r13745] Description: 
Take further advantage of the readers/writer locking in the metadata cache
and push the locking of the local heap up to the routines which call B-tree
routines, which should drastically lower the number of metadata cache protect/
unprotect calls.

Tested on:
    Mac OS X/32 10.4.9 (amazon)
    Linux/32 2.6 (chicago)
    Linux/64 2.6 (chicago2)
