This is not instead of killing, this is just a way to delay the killing of processes longer. Once your disk is full you'd still run into the choice between a deadlock and a kill... It's an awesome way of delaying the out of memory problem, though, because a suspended application won't be able to allocate anything more, giving the system a better chance to let the running apps run to completion. Alternatively, the one leaky application is suspended and the rest of the system continues to run without any problems. In short, I like it ;) regards, Rik -- IA64: a worthy successor to i860. http://www.surriel.com/ http://distro.conectiva.com/ Send all your spam to aardvark@nl.linux.org (spam digging piggy) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
