Comment (by teor):

 Here's how we might calculate a reasonable bandwidth for the self-test:
 1. Use 2 * NUM_SECONDS_ROLLING_MEASURE * min(RelayBandwidthRate,
 AuthDirGuardBWGuarantee) bytes
 2. Split those bytes into CIRCWINDOW_START cells per circuit
 3. But keep the number of circuits well below the DoS limits
 4. If there are extra cells left over, just split them evenly across the
 circuits
