I didn't invent that, I've heard laptop users complain about timers.

But okay, if it's acceptable to run a timer in order to re-enable
compilation when AC power is plugged in, I'm okay with such an
optional feature.  Patches are welcome.

You will see that comp.el already has a queue of files that await
compilation.  The new feature will newed to plug itself into that
mechanism, I think.  Unless Andrea has a better idea.
