The session table has very limited uses in 1.3.  If we are going to do
that, I would suggest doing so on a private copy first and run it for
a week or so before making the change global.

The session doesn't provide login access.  All it does is track
discretionary locks and open forms (for anti-xsrf measures).  It's not
critical to see a duplicate session, to be honest.
