 and document: that the per-service one works differently from the per-
 intropoint one; that one is for security and the other is to avoid
 redundant rendezvous; and that one lasts for the lifetime of the intro
 point while the other gets cleaned?  It seems error-prone to have two maps
 with similar names and documentation but with crucially different
 semantics.

 Done and pushed to my bug3460-v4 branch, along with documentation-comment
 fixes.

 Real Soon Now.  rend-spec.txt doesn't say what the timestamp field in an
 INTRODUCE* cell is for, so this Tor change doesn't actually make anything
 in rend-spec.txt wrong or obsolete.  I also see some other things that
 need to be fixed (the description of HidServAuth is wrong).


 I'm changing the milestone to 0.2.3.x-final, because you're not going to
 merge this change to 0.2.2.x.
