At this point it's hard to escape the conclusion that we're looking at
some sort of bug in the Windows version of the WaitEventSet infrastructure
--- or at least, the WaitEventSet-based waits for socket events are
evidently behaving differently from the implementation on the libpq side,
which is based on pqWaitTimed and thence pqSocketCheck and thence
Noticing that bowerbird builds with openssl, I'm a bit suspicious that
the issue might have something to do with the fact that pqSocketCheck
has a special case for SSL, which I don't think WaitEventSet knows about.
But I don't think SSL is actually active in the buildfarm run, so it's
hard to see how we get to that scenario exactly --- or even less why it
would only matter on Windows.
