It is a rather peculiar program though since it is a kind of

In experimenting with threads I found that a combination of
gobject.source_remove and gobject.idle_add can freeze the
application.
The program below will freeze on my machine if it is running
long enough. It does seem very sensitive to the sleeptime
value. Increasing that to 0.01 makes it less li

times and wait. But I didn't see any possibility
to include the program and the module on the

So how do I best report this bug?

I'm now writing a tube module to solve this. A Tube is like a Queue
but a thread has to open a tube before it can put or get things
on a tube and if all writers closed the tube a read from an empty
tube will generate an exception. But most off all there is a
tube_add_watch call which will monitor the tube like io_add_watch
