On second (third?) thought, I think I was right the first time. It
passes the flag WL_EXIT_ON_PM_DEATH (included in the
ConditionVariableWaitSet), so a WL_POSTMASTER_DEATH event should not be
returned.

Also, I think the early return is correct. The current code in
ConditionVariableTimedSleep() still checks the wait list even if
WaitLatch() returns WL_TIMEOUT (it ignores the return), but I don't see
why it can't early return true. For a socket event in
ConditionVariableEventSleep() I think it should early return false.
