And how else will you detect and recover from such a failure without a
timeout?  And are you absolutely certain that there will never be a
programming failure that will cause this loop to spin forever?

If you're really opposed to a timeout, you can still use
spin_event_timeout() by just setting the timeout to -1 and adding a
comment explaining why.
