    [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)
