[shib_auth] class registry in drupal 7 conflicting with shib sessions

[Andy Kohler]

We're not sure yet what part of the session overlaps between users.  A next
step for us is to reproduce the problem on the simplest possible system
(default core drupal + shib_auth + memcache), then we'll file a bug
report.  For now, through trial & error, the problem is 100% reproducible
with memcache enabled and 100% (so far...) fixed with memcache disabled.
But it may well be a combination of those things with others in our
environment, so I don't want to blame memcache (or shib_auth) at this point.
