-        while having acquired the mutex associated with the condvar and
-        ensuring that the signal's critical section happens after the waiter.
-        Thus, the mutex ensures that we see that waiter's __wseq increase.
-     2) Once we pick a position, we do not need to communicate this to the
-        program via a happens-before that we set up: First, any wake-up could
-        be a spurious wake-up, so the program must not interpret a wake-up as
-        an indication that the waiter happened before a particular signal;
-        second, a program cannot detect whether a waiter has not yet been
-        woken (i.e., it cannot distinguish between a non-woken waiter and one
