[Ltsp-discuss] Application suspend, force RAM to swap

[Roy Souther]

A few months ago I posted how I made an IceWM desktop session run under VNC to give people the ability to logout and keep their desktop running on the server so they can resume their session again later. This works great. I have it setup for a few teachers at the school but now I want to expand it and make it the default desktop for everyone. This will use a lot of RAM.

Is there any way to suspend or hibernate a single application, or is there anyway to force the Linux Kernel to move an application out of RAM and into swap and then just ignore it until told otherwise?

If I renice an application to +20 it still continues to use CPU resources, that's not good enough. I want to pause the program and all of the sub-processes that it spawned. And then un-pause it or wake it up again when the user resumes their desktop session.

Is this possible? Is there a kernel patch to do this? Should there be?
