But one has to be careful with this option. Sometimes it *is* a network or the
dying daemon on the host that cause lack of response and the job happily runs
to completion so restarting it might lead to confusion. Also users who
want to take advantage of this option should make sure that all their
file-writting transactions are done cleanly so the restarted job will not
continue writting to a file started by the previous job and produce
unexpected results.  I discovered the hard way that it created
more trouble than profit and we settled down for monitoring forced
