Right now, it's used for the presentations contrib which basically is
used to cache objects that have been sent to the repl. I was just
looking over this and it seems to be a bad idea to do this. I suppose
it makes te objects uninteractable after they've been in the repl long
enough, but a simple list might be a better way to do this. Wipe the
list when the repl gets cleared, and pop off a few entries if it gets
too long.

I'm going to ask the slime mailing list for advise about this.
