On my machine, DrRacket 5.3 [3m] (built from source package) looks like waiting for something for about 5-10 seconds when closing a tab that has a file open in it. It did not happen on Racket 5.2 [3m].
My machine's uname -a: Linux kire 2.6.32-41-generic #91-Ubuntu SMP Wed Jun 13 11:43:55 UTC 2012 x86_64 GNU/Linux (FYI, if a reply is needed, expect it to be late as I'll be on holiday until Aug 27.) ____________________ Racket Users list: http://lists.racket-lang.org/users
