I agree that it's a bit odd, but remember that after waiting on a CV's
latch, it needs to re-insert itself into the CV's wait list.
A WaitEventSetWait() can't do that, unless we move the details of re-
adding to the wait list into latch.c. I considered that, but latch.c
already implements the APIs for WaitEventSet and Latch, so it felt
complex to also make it responsible for ConditionVariable.
I'm open to suggestion.
