I won't make any attempt to understand the threading issues James
identified, but will point out for those python-dev readers unfamiliar with
GTK that its signals are really nothing like Unix signals.  It's more like a
software bus.  A GTK programmer attaches listeners to the bus and when the
appropriate signal comes down the bus listeners interested in that signal
respond.
