FWIW, we had code in the tree (just before the timeout_ch changes) that
did update all of the timeouts to 'fire' when the laptop was resumed.

This caused a 'thundering herd' problem at resume, but I don't see any
way around it...  However, it was lost when we changed to the different
timeout code.
