note 11546 added to set_time_limit

I've noticed that using this function doesn't seem to block things that make calls to services and wait for a response. Setting set_time_limit(2) and then making a call to gethostbyaddr(ip.that.does.not.resolve) just sits there until it times out. It would be -really- nice if there was a perl-esque type function like alarm() that lets you set timeouts for specific sections of code, rather than entire scripts. I'd have great use for a feature that would enable me to run non crucial pieces of code for a few seconds, and then give up and move on if it takes too long. http://www.php.net/manual/en/function.set-time-limit.php
