Comment:

 See
 [https://gitweb.torproject.org/rransom/tor.git/shortlog/refs/heads/bug3460-v4
 bug3460-v4] ( `https://git.torproject.org/rransom/tor.git bug3460-v4` )
 for a (not-yet-tested) fix.  This is a service-side change, and will need
 to be merged to master for testing before we decide whether to merge it to
 maint-0.2.2 .

 We should collect statistics on how often this branch expires intro
 points, and why they expired, but I haven't dug into the stats code yet.

 I'm CCing ‘atoruser’ on this ticket because this branch will need testing
 on a hidden service, and it is a prerequisite for the service-side fix for
 #3825.
