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.
