By the way, I raised a question about using multiple CVs
simultaneously [1]. That is, I suspect that the current CV
implementation doesn't allow us to use multiple condition variables at
the same time, because all CVs use the same PCPROC member cvWaitLink
to accommodate different waiter sets. If this assumption is correct,
we should resolve the issue before spreading more uses of CVs.
