It would be nice if it were possible to limit this. When the tests start up a bunch of browsers at the same time it can run smaller machines out of memory pretty quickly!

Or maybe what is happening is that the tests are not properly cleaning up when they are done and leaving old user agent processes around?

A little more data on this.... running the test collection against Chrome took just under 2 minutes on this server. Firefox took just under 20 minutes.

Yeah, Firefox's JIT is 💩. I filed a bug about Firefox being orders of magnitude slower than other browsers a few weeks ago. Unfortunately, it's not our code/tests that is the problem. For example, Safari runs the tests in under 20 seconds.
