runtests.py could detect if the interpreter process crashes

Would be faster than waiting for timeouts.

I've implemented a small change for my own code that makes a big difference: wrap the contents of read_to_prompt in:

try:
    ....
except KeyboardError:
    print 'Cancelled. Input so far:'
    print ''
    print self.buf
    exit(1)

And then change cleanup() to:

    def cleanup(self):
        #print "cleaning up"
        if self.p:
            try:
                os.killpg(self.p.pid, signal.SIGTERM)
            except OSError:
                pass
            self.p = None

Then you can ctrl+c out of something and see what happened. This is a HUGE improvement over the current usability, for a very trivial code change.

@boxed that's a good improvement for sure. I pushed a slight variation on that. Thanks.

Just pushed a fix that should resolve this. @tbu- can you confirm that it works for you?

Works for me, immediately errors out. Thanks for the fix.
