 It seems that the mainserver.cpp uses QWaitCondition-variables without
 proper predicative/counter. This means that if a pthread_cond_signal() is
 sent before the other thread has already called QT's waitCond.wait(), the
 receiver will miss the signal alltogether (see
 http://doc.trolltech.com/4.3/qwaitcondition.html examples of using counter
 with waitCond.wait()).

 The attached patch fixes this deadlock problem for good.
