Please use QemuThread.

- tp = find_trace_event_by_name(tname);
- if (tp) {
- tp->state = tstate;
- return true;

+ pthread_sigmask(SIG_SETMASK, &set, &oldset);
+ ret = pthread_create(&thread, &attr, writeout_thread, NULL);
+ pthread_sigmask(SIG_SETMASK, &oldset, NULL);
This is also taken care of by QemuThread.
