[racket] DrRacket 5.3 [3m] hangs for a while when closing tab with open file

I'm not seeing this behavior.

It may shed some light if you run the profiler. You can do that by
setting the PLTDRPROFILE environment variable (to anything), starting
up DrRacket, opening a file in a tab, clicking "start" in the
profiling window, and then closing the tab. The profiling window
should fill up with some helpful information.

One way to run with the environment variable set is via the command-line:

 env PLTDRPROFILE=1 drracket
