[racket-dev] Shared-instantiation modules

FWIW, this is one path that tools can use to circumvent DrRacket's
property (well, the property we work towards anyways) that no program
can cause DrRacket itself to crash or freeze. So if you do provide
things to the user's program in this manner, please try to keep that
invariant in mind.
