Good that we're on the same wavelength - I had a similar thought!

The annoying thing about Android, however, is that for an app to
continue to work in the background it needs to be coded in that way. I
suppose that if we were to treat Sugar as an 'appliance' UI (which is
how I tend to think about it), this isn't such a bad idea.

A quick hack would be to limit the number of activities that can run
simultaneously.

Our next OS will likely have the Dextrose resource monitor [1]. I
don't think we should be expecting children to be managing their
system resources, though. It should 'just work'.

I'll check with our education team and get back to you. This is a very
valuable discussion to have!
