The existing functions pthread_single_np() and pthread_multi_np(), which formerly had no effect, now exhibit the same behaviour and pthread_suspend_all_np() and pthread_resume_all_np(). These functions have been added mostly for the native java port. Don't allow the uthread kernel pipe to use the same descriptors as stdio. Mostily submitted by Oswald Buddenhagen <ossi@kde.org>.
