It was a disaster.... and the feature is overrated anyway. I was actually heavily involved with linux back in those days and I used this select() feature myself, but the disadvantages outweighed the advantages by an order of magnitude. It really isn't all that expensive to do a separate gettimeofday() system call. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
