[plt-scheme] shared state across multiple REPLs

This is (somewhat) by design. It is the same basic problem as the
history in your shell when you run multiple xterms in X11. Eventually,
there must only be one history that is saved when DrScheme exits. I
chose to make only one history ever and all interactions get put at the
end of that single history. You'll find that if you hit meta-p one more
time at the end of the sequence you describe below, you'll get (foo).

If you'd rather something else, I'm all ears, do be sure to explain
what happens after restarting drscheme.
