That is the jist of your changes. Poul-Henning's request was for a facility to possibly give you more space near the edge to work your way away from it. In otherwords, you might thrash less or recover more quickly from a low memory situation if you tell the rest of the kernel to free up data that can be recreated on demand. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
