Hello!
Since the beginning of the year a warning about an expired timeout has
been seen a few times.
It is most likely to observe this under a heavy load, when many threads
are exiting.
The propose is to increase the timeout.
The rationale is that if an application needs more time for the threads
to exit, let's give it that time.
Rather than just bumping the timeout a little I would suggest bumping
it a lot - make it a few minutes. If that fails then it suggests we
have a real problem not just a slow or loaded machine. Otherwise if
we just keep bumping the timeout it serves no purpose.
Alright. Then let's make it 5 minutes for both product and debug bits:

Thumbs up. If I remember correctly, we'll only hit the
5 minute timeout if we end up with the bottleneck where
too many threads are queued up to leave... and none of
the threads that are leaving make progress...
