The slowness of the builders only means that we do fewer builds. So when the
bot turns red, the regression window is large. For the most part, we don't
actually fall behind on the builders. The problem is that the build is
*much* faster than running the tests. So we often end up in a situation
where the build finishes in a reasonable amount of time, but the tests don't
run for hours because we have a number of builds queued up. I've literally
waited 10 hours after the build has completed for the tests to run.

The build time could use an improvement, but it's minor in comparison to the
time to run tests.
