Last sprint the buildbot got overwhelmed with a giant backlog of runs and became essentially useless for the duration of the sprint. Jean-Paul had two suggestions:
  1. Don't commit to trunk during the sprint, even if your branch was approved; wait until the sprint is over so trunk commits are spread out.
  2. If you're just doing some initial cross-platform testing using, use the command line option that lets you run only some of the tests (e.g. "twisted.web" or "twisted.python.test.test_versions") instead of running the whole test suite.
