Idea: powersaving window manager

Description

Processes like firefox and thunderbird often consume substantial CPU and therefore battery even when minimized.

One can sleep processes by hand using

pkill -SIGSTOP firefox

and wake them up with

pkill -SIGCONT firefox

This often gives me battery savings of 50% !

It would be even nicer to integrate this behaviour in the window-manager. The idea is to SIGSTOP programmes when minimized and wake them up when unminimized. A white/blacklist would determine which programmes are treated this way.
