Description of problem:
If a remote NFS server is down, "umount -f" doesn't work.

Version-Release number of selected component (if applicable):

How reproducible:
Always, I think.

Steps to Reproduce:
1. Mount an NFS file system using options rw,bg,hard
2. Disconnect or stop the remote server
3. On the NFS client system, try to unmount the filesystem using "unmount -f"
Actual results:
Cannot MOUNTPROG RPC: RPC: Port mapper failure - RPC: Unable to receive

Expected results:
umount should work.

Does this happen with RHL9? How about if you soft-mount it instead?

Steve, if this looks familiar can you comment on it? If it's not,
please just close it out as it's a really old bug.
