We could do this even without an advanced reporting mechanism. The
monitoring code in the CPU & Memory meter could detect memory shortage
and automatically quit  the least recently used activity.

Or, maybe, we could make this a manual process: pop up a notification
when memory is short and ask which activity should be closed.

A while ago, Tincho has been working on implementing the Freedesktop
notification protocol in Sugar. This feature didn't make it for
Dextrose, but perhaps it could be completed in time to be merged into
0.90.
