I noticed Firefox getting janky not long after startup and discovered that TestPilot's remote-experiment-loader.js was monopolizing the main thread for about 600ms. From looking at the profile alone, it looks like the time is being spent opening a Zip archive and checking file mtimes.

TestPilot version 1.2.2
We should look into moving some of the I/O off the main thread. I'm told it's not currently possible to open archives off the main thread.

Fixed by removing test pilot 1. Any new versions we integrate should not have this kind of problem.
