> Straw-person proposal:
> 1. Begin with a timer interval of 5s.
> 2. After throwing away a backing store, record the time interval required for the next paint.
> 3. Update the timer interval to 100 * the recorded time interval in 2.
> For fast-painting sites, this will throw backing stores away quickly. For slow-painting sites, this will approximate a maximum thrash cost of 1%.

I punted steps 2 and 3 out to bug 55733.
