21   - mapping from IP address to client name
22   - mapping from client name and filesystem to export options
23   - mapping from UID to list of GIDs, to work around NFS's limitation
25   - mappings between local UID/GID and remote UID/GID for sites that
27   - mapping from network identify to public key for crypto authentication.
31    - general cache lookup with correct locking
32    - supporting 'NEGATIVE' as well as positive entries
33    - allowing an EXPIRED time on cache items, and removing
34      items after they expire, and are no longer in-use.
35    - making requests to user-space to fill in cache entries
36    - allowing user-space to directly set entries in the cache
37    - delaying RPC requests that depend on as-yet incomplete
40    - clean out old entries as they expire.
