Fix usage of condition variable in TQThread which could lead to a thread being run multiple times in parallel.
Although highly unlikely, the following situation was possible:
- a thread is restarted while still running. The call to the second 'start()' blocks because the thread is still running
- the OS decides to randomly wake up the thread that called 'start()'
- a second thread is started and runs in parallel to the first thread, with obvious undefined behavior
