    I don't think it's all that difficult to make kill -9 work even if a
    program is stuck in a hard mounted NFS operation.   I would agree
    with such a change if it were submitted, as long as (like with 'intr'
    mounts) the signal does not abort the operation until NFS has gone
    through a few retries.  Maybe we could call it the 'medium well done'
    option.  Not too hard, not too soft :-).
