non-nfs things hang on nfs errors

The Scenario: a 3/180 named stpstn and a 3/50 named fozzie (for example)
(both 3.2) Pretty much everything with a disk drive is cross mounted, and
fozzie's /usr is mounted on stpstn. I find that when I'm on stpstn (or
any machine that has a remote partition mounted), and a remote server
stops responding (crash, retensioning a scsi tape, etc...), whatever I'm
doing hangs with "server foo not responding" until either the remote
server responds or I reboot the local machine. df is a good example, but
it also happens if I'm doing something that isn't even remotely nfs
related. Am I doing something wrong or is this an inherent problem?
[[ This is an inherent and well-known problem. Things that don't appear
to be NFS related will actually get snarled in this trap. If all your NFS
mount points are in the same directory, say "/", simple things like "pwd"
or a program calling "getwd" will, in certain situations, lock up. --wnl
