#9543: weird behaviour when MaxCircuitDirtiness is set to a high value

 I tested this with the rttprober script[0] which opens circuits and
 attaches multiple streams to them. Each stream connects to 127.0.0.1,
 fails and quits. When I set MaxCircuitDirtiness to the default value (600)
 and tell the script to open circuits and run 1000 stream-probes on each
 circuit, it completes for most of the circuits. When I set
 MaxCircuitDirtiness to a very large value (tested with 2147483647 and
 1073741823) almost all circuits where closed with reason FINISHED before
 all probes where run. Using a MaxCircuitDirtiness of 10000 works as
 expected though.
