According to [1], all python needs to do to avoid this problem is block all signals in all but the main thread; then we can guarantee signal handlers are always called from the main thread, and pygtk doesn't need a timeout.

But I would really prefer the first alternative, as it could be fixed within python 2.5; no need to wait for 2.6.

Assuming "the first alternative" is the "just block all signals in all but the main thread" option, there is absolutely no chance of this going into 2.5.

Signals and threads combined are an complete nightmare of platform-specific behaviour. I'm -1000 on trying to change this code now, after the first release candidate. To say that "that path lies madness" is like saying "Pacific Ocean large, wet, full of fish".
