Another bug.  The CAS loop in pthread_cond_signal() could race against the
thread it is trying to awake.  The thread could exit the condvar and then
reinsert itself at the head of the list with a new waiter behind it.  It's
likely possible to fix this in a way that's wait-free but for now just fix
the bug.
