deadLock between QT app and qnx screen process at startup

[Marcos P.]

hi, we found that randomly our QT app on QNX hang on startup, screen is shown but it hang and don´t respond to touchscreen or refresh anymore.
We found also that our App process is blocked on a semaphore and screen process too, it looks as a deadlock for us (watch the captures).
Killing and launching again both process solve the problem but is not a valid workaround for us.
