Related stupid questions:

   1. Does setting LDAPSharedCacheSize to 0 disable shared memory but
      not the cache?  [The docs say so.]
   2. If so, then wouldn't we want to use per-process read/write locks
      in this case and global mutexes only when shared memory was
      actually being used?
