Comment:

 As of now, I have 17 *very useful* tracepoints mostly in the hidden
 service subsystem. I don't think they are ready to be merged right now
 since we have yet to prove that all of them are useful to our performance
 measurement and that the data they record is actually what we really need
 (or any missing).

 I suggest we move that to 0.2.7 because I would like to see that upstream
 soonish but with more eyes on the usefulness of the tracepoints. I think
 next tor dev. meeting, we should take a couple of minutes to discuss this
 in person with real use case I can demonstrate.
