Not sure.  This might be paranoia or leftovers from an earlier version of
the code that didn't use signals.

Sounds plausible to me.

But the signal code does cause shutDown() to be called on Windows, so it's
not necessary to call it after returning from mainloop because it's the call
to shutDown() that _caused_ mainloop to exit.

You do have a point that if the mainloop exits for some other reason than
Ctrl-C being called, then it looks like shutDown() won't be called.  This is
where your proposed test to see if we're still running might help.  In
practice, I can definitely vouch that the existing code for Windows seems to
work properly.

This code is all kind of messy.  If you can figure out how to clean it up
without breaking anything, more power to you :-)  It's difficult to do a
good job because things work a little differently on Windows vs. Unix.
