------------------------+---------------------------------------------------
 Currently, Tor clients do not clear their hidden service descriptor cache
 when they process a SIGNAL NEWNYM control port command.  Thus, anyone who
 can ‘tag’ a client with a unique HS descriptor, and then test for the
 presence of that descriptor later, can track the client until the
 descriptor expires up to 72 hours later or until it is stopped and
 restarted, whichever happens first.  We should fix this.
