This won't help you now, but if you run in to this problem a lot
because of an unreliable network, unreliable server, or whatever,
you might want to mount your NFS shares with the "soft" option.
Shares mounted in this way are easier to deal with when the server
is unavailable. Any attempt to access the NFS file system will
time out instead of hang.

There are supposedly some down sides with the "soft" option. The man
page is vague about this, but I suspect it has to do with undesirable 
timeouts resulting from a merely busy network or server as opposed to 
something actually being down.
