Ok, I've just wrote Stall() and Sleep() operators. Differences
between them are short-term or long-term, not relinquish CPU or
relinquish CPU. I used DELAY() for StallOp and tsleep() for SleepOp.
BTW, is timeout parameter of tsleep broken for now? I had to call
wakeup() explicitly, otherwise it won't return from tsleep :-(
