I added an underway() method that gets you a set of underway jobs, each
with its job spec, deferred, and start time. I guess you could add
callbacks or timeouts to the set of outstanding deferreds (e.g., for some
reason you're about to pause and you know the currently outstanding jobs
are going to fail or are somehow invalid and that you're going to have to
redo them, so you could add a callback to each to put it back on the queue,
and then call pause).

OK, added an assert to make sure you can't do this.
I'm not sure the details of all this are of interest to many people on the
list. I'll find time to put the code up somewhere more useful. It would be
nice to have a runnable demo/example too. Not sure I'll get there.
