interrupted with a SIGALRM. In fact, select() sets the passed time to zero, making the previous implementation terminate always after 1/10th of a second ! Also, deal with someone changing the clock while we're sleeping (and restart the whole sleep). Dangers pointed out by: Theo de Raadt <deraadt@cvs.openbsd.org>
