[racket] Racket v5.3.2

FYI.

Since starting with 5.3.2 I've seen two DrDracket crashes (Windows7 - 64
bit).  Hard to determine the cause in both case I believe I had just
clicked in the definitions pane when it hung and Windows told me that
DrRacket was not responding.

I have spent about 4 hours in DrRacket, so the crashes are somewhat rare,
although I didn't see any in 5.3.1.
