Has anyone had time to test David's patch? If yes have you had
any problems since?
I should know later today if the other person who had been reporting
problems has had them stop. He reported last night he was still able
to reproduce the problem but he hasn't had any "luck" doing it today.
David, my only real question I guess is whether perhaps P_STOPPED_SINGLE
should be added to the flags that are being turned off by your patch.
If I'm following the code right what had made P_STOPPED_TRACE special
was it's one of the three signals lumped into P_STOPPED and the code
in do_tdsignal() looks for that, as well as I'm sure the schedulers...
