I don't know of any Tkinter or PyQt equivalent.  I hope somebody can
enlighten me about those, as they're the toolkits I need to use.

<nod> yep.  And figure out something similar for asyncore/asynchat or
other packages that use a select -- that would be just the ticket.  All
the modification needed to Queue would be an optional callable to call
when the queue transitions from empty to non-empty -- different ones
could be supplied for various GUI kits, async*, etc.
