    Think about some very important work being run on NFS-mounted file,
    and server is brought down while you're at lunch. I much prefer
    client to hang forever (i.e., no 'soft' option!), waiting for admin
    to take action.

    I use 'hard,intr' so admin can kill 'hung' processed if (s)he wants to.
