Here's Hixie's suggestions:

* Number of times setTimeout() or setInterval() are called with values less
than 10, bucketed per value
* Number of times a timeout callback runs long enough that by the time it
completes another timer has already fired
* Number of times the callback of a setTimeout(n) chains to a setTimeout(m),
where n, m < 10

And my own addition to that last one would be, the amount of time it takes
the callback to execute once.

I suppose we could also count the total number of setTimeout() calls we see
in order to display these values as "fractions of all setTimeout calls"?
