Comment(by mikeperry):

 I wrote some example end-to-end probing code for #7691. Could easily be
 generalized/adapted for stream timing data collection.

 Also note that for purposes of things like #7691, we do not want any
 activity we *always* do over a circuit to cause it to be counted as
 "successfully used". Otherwise, path bias attackers can anticipate this
 activity and let it through before failing the circuit.
