Hmm… AFAIU it’s not allowed to raise process priority above some

As a practice shows, non-root user may raise it’s priority in QNX4 up to 19
which is IMHO more then enough to make some significant troubles for the
whole system. For example:
main() {
setprio(0, 19);
for (;
fork();
}
…almost kills it.
