A wakeup once every half hour would surely not be an issue from a power

we trying to remove the timeouts completely?
Well, in the case of the AV launcher, the issue is that the main loop
is timed by definition, cf. autovacuum_naptime, and the WaitLatch()
interface is apparently designed so that we can't sleep longer than 35
minutes.
Hmm. Well, it's not too late to rethink the WaitLatch API, if we think
that that might be a significant limitation.
Right, we can easily change the timeout argument to be in milliseconds
instead of microseconds.
