asyncio_subprocess_watchdog.patch:
* add test_asyncio.watchdog.setup_watchdog(): use
faulthandler.dump_traceback_later() to kill the process if it hangs more than
'timeout' seconds (do nothing if faulthandler is not present, eg. on other
Python VMs than
Guido van Rossum added the comment:
Hmm... When did you last see the hang? We've had a variety of checkins that
might have affected this code.

minority platforms!

Oh, I didn't notice that test_subprocess_send_signal() is part of a mixin:
SubprocessTestsMixin. Configure output:
checking sys/devpoll.h usability... no

Guido van Rossum added the comment:
Oh, sorry, I didn't realize the name of the failing test was in the issue
title. But even that's no excuse, because it's also in the log. :-(
Fortunately the line where we're hanging is also in the log: line 291 in
selectors.py is in PollSelector. So that's
