Jigsaw Shutdown Hook

Hi, I sent the following message to the list last week, and received to
responses. I did a little more research into the problem and concluded that
there is no way to receive notification that Jigsaw is shutting down
gracefully. The problem is, we (my company) have written several extensions
to Jigsaw that spawn their own threads and run until Jigsaw exits, but that
need to cleanup after themselves. There are a few possible kludges, but I
think the best way to do it is to have Jigsaw have a hook that allows you
to be notified of shutdown.

For now, I've settled on the following kludge: I've extended the Exit
resource (w3c.jigsaw.status.ExitStat) so that it calls notifiers when
someone clicks on it. Of course, this means we have to replace the Exit
resource on every copy of Jigsaw that's running our extensions...not fun.

I think that this functionality would be a good addition to Jigsaw, so I'm
respectfully re-submitting my request for it.
