Am I understanding this correctly? Right now I'm running into a problem where watchpoint is being set while the state is eStateRunning. That's a probably caused by an unrelated problem of threads failing to be stopped.

Yes, it's safe to send PTRACE request to a thread when it in stopped state. How do you reproduce this situation with setting watchpoint on a running thread?
