That's right, but spurious wakeups would be a good argument against
accepting such an implementation. Or that implementation should be fixed
to avoid them.

That said, we couldn't use the POSIX implementation anyway, since our
API allows the user to choose the type of lock, while POSIX AFAICT would
only accept a POSIX mutex (which doesn't have the same semantics as an
arbitrary Python lock).
