Hi Eliot,

On Ubunutu 13.10, All Seaside 3.1.1 & Grease 1.1.0 tests, no browser open

Spur v3000:  11445ms

Cog v3000:   9675ms

On every platform so far the profiler output just shows that they both spend
most of their time updating the progress bar the test runner displays.  

Hope this helps and let me know what else you want to see.
