Saying that it locks up the whole machine is probably overstating things a
bit. As long as you don't try to access any NFS when a server goes down,
you're fine; this means, for example, that you can login as root and
shutdown/restart (as long as the .profile/.login/.cshrc isn't using stuff
from an NFS server!).
Using amd(8) will help to alleviate the problem, since the mounts are
only made when you need them. You incur a small performance penalty for
the initial mount, but in my experience this is worth the somewhat
increased reliability of the system.
