KeyboardInterrupt (any interrupt really) is dangerous. Now, we can probably code a solution, but how about we remove the danger
The other day I accidentally fork-bombed myself with Python os.fork in an infinite loop. Whoops. It seems to me that Python's design philosophy is to make the safe things beautiful and efficient, but not to remove the dangerous things.
I'd be supportive of a proposal that makes threading safer without removing capabilities for those that want them.
