Description: decrease failure rate of QProcess (#561203) on hppa ~100+ times
 The patch adds a usleep() of 1000 before fork() in QProcess on hppa. This hack
 seems to bring down likelihood of failure caused by #561203 from ~ 1/6 to
~1/1000 when run in a row. Hopefully, this will make failures rare enough
 not to cause FTBFSes.
 Degradation in performance should not be very significant and is acceptable.
