If you want to be strictly accurate:

1. MBX locking rules use fcntl() locks.

2. fcntl() locks don't work over NFS when more than one host has
                                     ---------------------------
   access to the NFS server.
   ------------------------


Actually, it isn't that the locks don't work, it's that the cached data
from the server that is held inside the client is not refreshed when a
lock is granted after a wait.
