Why does rpc.lockd(8) and rpc.stat(8) require a working Internet connection

[Aryeh Friedman]

My cable modem was out for a few hours last night and my NFS based *LOCAL*
(same subnet [192.168.11.XXX] and physical LAN) file server started
glitching up on attempting to contact lockd and statd on the server from
the client(s) saying that the service was non-responsive and/or the server
couldn't be found.   I attempted to switch over to /etc/hosts based host
resolution to no avail.   I also tried switching to purely IP addr based
connections to no avail.   Note NIS/YP kept working.

Several questions:

1. How do I make it so I can completely disconnect my LAN from the rest of
the Internet and not have NFS fail like this

2. Why does NFS require a live internet connection?
