Can you explain how you know (2) is completed before (3) occurs, in your
scenario? If there's no synchronization to order these steps, then isn't it
possible that one or more of the signals happens after a thread from group B is
waiting?
If you have a minimal self-contained test case for the issue, I'd be interested
in seeing it.
