It's much too hard to debug the common error of leaking timers, especially
setInterval() timers right now.  As a developer I want to be
able to click a button in the inspector and have it list out every pending
timer along with:

- whether it's a setTimeout or a setInterval
- the delay time specified and the clamped value
- how many times it has fired so far (for setIntervals)
- a timestamp and the JS stacktrace when it was set
- what code will be executed when it fires (either the specified string or
the contents of the specified function)

This would make debugging a few recent problems in google properties about
10,000,000x easier.
