So I think I have an alternative implementation that ought to be more straightforward to port to MS Windows if ever that is necessary, one that I think (hope) is safe:
https://github.com/RJVB/shortcut-test-qt5/blob/master/main.cpp#L96 This uses a single semaphore and a QtConcurrent background thread that "monitors" it. I think it's hardly more complex than using the pipe+QSocketNotifier solution (and could be simpler if it weren't apparently a good idea to destroy the semaphore before exiting). Curiously, the manpage suggest that sem_wait() should be interrupted by a signal, and that's indeed the case in a single-threaded test-case. Pity, because it would have made the call to sem_post() superfluous in the actual signal handler...
