A trick I've learned is to either mount the NFS drives with the "soft" 
option, or with "hard,intr".  In either case, this should allows 
operations to fail and exit when the server goes down.

For some reason, the docs say that the latter is recommended.  I had always 
used the former with no bad effects.  Check the docs for the "intr" option 
as I'm not sure I spelled it right.
