I'm trying to look for correlations in certain iOS test failures.  To do this, I'm playing with the task list in the swarming UI.

It happens that I'd like to look at the set of tasks that timed out after exactly 1h, sorted by time.  To do this, I am:
1) Sorting the list descending by timestamp.
2) Then sorting the list by duration.

I was hoping that the sort would be stable, so that all of the "1h" tasks would continue to be sorted by timestamp, but they look all jumbled up.

Would it be possible to use a stable sort in the task list, to allow for analysis like this?
