#include <time.h>

int	mysleep(int seconds) {
	struct timeval	tv;

	tv.tv_sec = seconds;
	tv.tv_usec = 0;
	select(0, NULL, NULL, NULL, &tv);
	return(tv.tv_sec);
}

That should emulate sleep() pretty well. If the mysleep() call is
interrupted during the select(), it'll return the number of seconds
remaining in the sleep timeout, just like the standard sleep() does.
