Oh, regrtest main process was killed by faulthandler watchdog: it was blocked in _get_result() for longer than 1 minute.

Extract of _get_result():

    use_faulthandler = (self.ns.timeout is not None)
    timeout = PROGRESS_UPDATE
    while True:
        if use_faulthandler:
            faulthandler.dump_traceback_later(timeout * 2.0, exit=True)

        # wait for a thread
        try:
            return self.output.get(timeout=timeout)
        except queue.Empty:
            pass

        # display progress
        running = get_running(self.workers)
        if running and not self.ns.pgo:
            self.log('running: %s' % ', '.join(running))

self.ns.timeout is supposed to be 1500.

I don't understand why regrtest got a timeout of 60 seconds?
