aFake a SIGINT happening during Popen._communicate() and ._wait().

        This avoids the need to actually try and get test environments to send
        and receive signals reliably across platforms.  The net effect of a ^C
        happening during a blocking subprocess execution which we want to clean
        up from is a KeyboardInterrupt coming out of communicate() or wait().
