This is definitely the way it should work.

Thanks, Brian, for taking the time to analyze the existing cReactor code in so
much depth.  I really owe you one.  I will need more time to fully read and
comprehend the rest of the message, but this part has been on my personal TODO
list for a while.

Ideally, I'd prefer that the reactor is *always* in a consistent state.  That
would probably involve redefining or removing the "crash" facility, since there
would only be "pause and return so that run() continues" or "stop properly so
run() restarts".  Whatever compromise you come up with in this vein is probably
acceptable, though.
