[racket] Racket v5.3.1

Congrats on another release.

Anyone know whether any serious bugs were fixed in this release?  (I 
don't see how to query this from the bugs database.)

Reason I ask is to help decide how soon to move production apps to 
5.3.1.  (Serious bug fix might mean soon; otherwise, good to let hapless 
other people possibly shake out any new bugs.)
