New description:
I don't think this is HSv3 ONLY related, but I can only make it happen
while building large amounts of rendezvous circuits with reasonable
concurrency (over 50). I am not assigning the tor-hs keyword for this
reason, but sticking it to same master parent ticket.
All lines are the same. It is seen for like 130-160 times during the build
of little over 100.000 rendezvous circuits.

EDIT: All lines are the same except it always abandons 0 out of N circuits
and N is always different of course, increasing with +1 most of the times
until the Bug warn disappears.
