Idea: powersaving window manager

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.
