Yeah. The perfectionist in me wants to say that there should be
explicit wakeups for every event of interest, in which case there's
no need for a timeout. The engineer in me says "but what about bugs?".
Better a slow reaction than never reacting at all. OTOH, then you
have to have a discussion about whether 60s (or any other
ice-cap-friendly value) is an acceptable response time even in the
presence of bugs.
It's kind of moot until we've reached the point where we can
credibly claim to have explicit wakeups for every event of
interest. I don't think we're very close to that today, and
I do think we should try to get closer. There may come a point
of diminishing returns though.
