[racket] drracket editor running too slow

Just for the record, I've been using a one-week old version nightly
built of 5.1 on Ubuntu 10.04 daily during last week and didn't
experience any slowdowns. (on a reasonably fast 2.6 GHz i7 920 with 6GB
RAM, though)

So the slowdown must be specific to Ubuntu 10.10 or your configuration.
