~331 vs. ~630ms. A pretty significant win (2x).
Mårten noticed that on Windows, condition_variable::wait_for(x, 0ms)
will not unlock the mutex, which, however, the program requires, so
use a 1ns timeout instead.
Drive-by fixes:
- add override to run() reimplementations
- fix type of timeout member variable (was int, should be unsigned long)
- fix naming of test functions to distinguish better between QMutex
and std::mutex
