While that behavior is theoretically possible, I've heard no field
complaints about it actually happening.  I don't think we should
move heaven and earth to prevent it, barring some evidence of it
being a real-world issue.

ISTM we do need to do something about this AcquireExternalFD failure
though, because that's just self-inflicted damage.  (And I think it's
likely new since we invented WaitEventSets, though perhaps I'm wrong
about that.)
