I just did a little investigating here.  The problem is that
there's no hook in the current preference implementation to
perform a "cleanup" operation.  In this case, the 'horde_prefs'
session variable needs to be unregistered.

For the time being, unregistering it in IMP's logout routine
should work fine.  We also have a notion of a Horde logout, so we
can unregister it there.

However, this begs the question of whether we should add a
generic "cleanup" routine to the preference drivers that each
could implement in their own way.  It seems like a good idea to
me.  Any comments or objections?
