A related thing I came across the other day: systemd has a new
sd_notify() functionality EXTEND_TIMEOUT_USEC where the service can
notify systemd to extend the timeout.  I think that's the same idea:
You want to timeout if you're stuck, but you want to keep going as long
as you're doing useful work.

So yes, improving that would be welcome.
