This is cool but doesn't sort exactly right - it only sorts by the first digit in the completion time - report actions taking in the double digits don't fall in line.

I guess that's motivation to get all actions in the single digits :)

The -n flag on the sort command sorts by numeric rather than by character. It works on my box (Linux/Gentoo)

Then again, I don't have anything beyond double digits in the test log.

This line can be added to a script, such as script/analyze_logs for convenience.
