Right, and what I was wondering was whether adding the additional wait-for
condition had exposed some pre-existing flaw in the Windows latch code.
But that's not it, so we're left with the conclusion that we broke

Are we sure this is a 9.5-only bug?  Shay, can you try 9.4 branch tip
and see if it misbehaves?  Can anyone else reproduce the problem?
