It appears I've run up against a deficiency in pyglib. Maybe there is a
work around?
Take the case of trying to schedule an idle callback to run in another
thread's main loop. An illustration in C...

I'm repetitively calling g_idle_source_new(), g_source_set_callback(),
g_source_attach() to get an idle callback to run in a separate thread. The

The docs for GSourceFunc() state:

Have you tried a "flush" operation. ie fflush() or g_io_channel_flush()?
Beyond that we would need to see some sort of code example.
