[racket-dev] Can't change plot in DrRacket without getting link errors

Yes: as an experiment we decided to treat files that are open differently
than other files for the purposes of recompiling them.

Looks like that's probably a bad design decision. But it may just be a bug
too, since I thought it was re-compiling more, not less, when you have the
file open.
