   torflow/trunk/CircuitAnalysis/BuildTimes/full_run.sh
Log:

Add the ability to run soat/speedracer runs concurrently with
the buildtimes runs. Rawk. Also add some checks on the router
list rankings. Hit some bug after approx 200k circuits where
the rankings blipped out for a bit (or we stored them wrong,
or python had some braindamage..)
