multiprocessing-keyboardinterrupt's Issues

Only works within 1st 10 seconds

For this code to work on other projects, it seems that the keyboard interrupt needs to be received within the first 10 seconds - after that python hangs. Or the 10s sleep time needs to be increased. Am I missing something?

Doesn't always work on Windows

I'd need some more testing, but I tried the same approach on a larger project and it doesn't always seem to work - sometimes the KeyboardInterrupt exception is received by the main process but sometimes it's ignored entirely.

What did work for me was much more complicated. It involved patching the multiprocessing library on runtime to modify the command line that's used when spawning new processes, and starting up new processes from my own code. Then catching the SIGINT signal from there in every spawned process and explicitly killing all spawned processes.

I was hoping to avoid all that by using your much more elegant approach :( I'l keep digging in case it turns out to be a mistake on my side, but in any case I thought documenting it would be useful in case someone else stumbles upon the same problem.
