I'd recomend that lock management, if done, be done just like nfs, IN THE KERNEL.
Sun had addopted this approach and has given up on the stupid approach of doing
it in a User Sparce daemon. It's actually much simplier than NFS.  Also, I'd
recomend implementing the SYNCHRONOUS version, at least in addition to the
STUPID ASYNC version. You can get around the problem to the lockd server
sending RPC's by have the number of lockd`s running in kernel space dynamicly
adjust to the needs, always leaving a lockd or two to handle incoming RPC's.
