Have you tried "umount -l"? How far is that from your requirements?
Alternately: mount --move /problem/path /somewhere/else umount -f /somewhere/else umount -l /somewhere/else
might be a little closer to what you want.
Though I agree that it would be nice if we could convince all subsequent requests to a server to fail EIO instead of just the currently active ones. I'm not sure that just changing "umount -f" is the right interface though.... Maybe if all the server handles appeared in sysfs and have an attribute which you could set to cause all requests to fail...
