This is essentially what the mainframe folks are already doing and have been doing for some time because the kernel VM has no external inputs for saying "you are virtualised so be nice" for doing opportunistic page recycling ("I dont need this page but when I ask for it back please tell me if you trashed the content") and for hinting to the underlying VM what pages are best blasted out of existance first and how to communicate so we dont page them back in scanning them. ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
