How about sharing timers? I can easily imagine 10-20 engines with 1s timeout.
That could reduce the number of wakeups significantly.

And maybe a global power saving mode. When enabled reduce the number of
updates of cpu utilization and network traffic diagrams and disable
seconds in clocks etc.

For a lot of data engines (e.g. for stuff from /proc or /sys) the update
rate is rather arbitrary and may be different for different applets. I
don't think the current api can really handle this.
