If a user leaves Firefox open on a site with a flash graphic going it is going to just site there and use up large amounts of resources for not use at all.
I can run a script to re-nice all the processes owned by the user but will not be very useful at all. The problem with nice is that you can only lower the priority of an app a little, not enough to make any significant difference at all.

Is there a kernel patch to do this? Should there be? There's no patch that I know of, to take individual processes and suspend them. Only entire systems, like laptops when you hibernate them. If Icewm is still taking resources while idle, it's likely because Icewm by default has a couple of applets running, like the net-monitor and clock on the taskbar. The network-monitor will cause alot of network and cpu resources to be used, and the clock will also do that. If your clock is displaying seconds, it'll do that once every second. In Icewm, it's not hard to change the clock display to only show hours:minutes. That could help alot. Once the application is idle (I mean really idle), then the VM subsystem in the kernel will take care of swapping it out, if it determines that the ram can be better used for something else (other processes, disk buffers, etc). So, basically, figure out what's still running within Icewm, and tell it not to run. That'll make it go idle, and eventually swap out.
