     [extremely shocked pause...]
     Roger, please tell me that you're joking.  I have *never* had the
understanding from reading the documentation in all of the years I've been
using tor that only a single line of each type would be used.  How, then,
are we to exclude all of the nodes that we find unacceptable for use in our
own circuits?
     If what you say is actually the case, then it would seem that a problem
described on this list on many occasions during the last few years may, in
fact, have been due to this horrible limitation.  Several of us have complained
on numerous occasions that adding a node to one list or the other and sending
SIGHUP to tor (or restarting it) failed to prevent that node from being used
in the manner that we had expressly excluded.  If what you say is indeed the
case, then it is a truly awful design bug.
>Can you confirm?
     I'm not a tor developer, so no, I cannot confirm.
