[racket] DrRacket sluggishness since upgrading to 5.3.1 (OS X 10.6.8, 64-bit build)

Some of the changes are, but I'm not sure exactly when the version
number bump happened wrt to the changes I've committed.

I don't think I fixed anything having those symptoms, tho.

It sounds like there is a leak somewhere. Does it happen if you are
just editing, and not running your program?
