One thing you could do is process the key_up_event rather than the
key_press_event. That still doesn't help if the user presses the key a
bunch of times.

Any chance of forking or cloning, returning immediately and doing the
work the button triggers in the background? Of course, you have to be
careful what you do at the GUI level in a thread.

Maybe there's some way to disable the signal when you enter the
handler and re-enable it when you exit it? This would actually be way
useful functionality hmm. I'll have to see if it's possible to do
this...
