There is no solution. This is a problem inherent in the way python handles the GIL, c extensions, and Signals. Details here: http://www.dabeaz.com/python/GIL.pdf see slide 22

Hello -- I've got a python script with C++ extensions. Some of my extensions take a long time to complete, and I don't want to wait for them to finish when I'm debugging stuff. However, when I do Ctrl-C in my terminal, it's completely ignored. So it looks like python is trapping the signal, but apparently can't do anything with it until the extension returns control to the python script. I guess ideally, Ctrl-C would kill the extension and return control to python, generating an exception, but I'd also be ok if Ctrl-C killed the python script too. I've been googling around, but can't figure out how this seemingly simple (and desired) task is accomplished. Anybody know how to do it? Right now, the only solution is Ctrl-Z and kill %1 so I guess that works for now... thanks!
