How quickly do the object memories diverge?  Would a full garbage
collect screw this up, or is old space pretty stable?  I posted
recently on the Seaside list thinking about a model where we forked a
Squeak image for each session, but with the qualifier "once we have
some nice small images".  But maybe that's not necessary?
