Ubuntu has had ASLR enabled by default since 10.04 (about five years). 
During that time, in my experience, it's never affected Racket.

I do have to use "setarch i686 -R" to disable ASLR to run Maxima, which 
is written in Common Lisp. So it's a problem for some GC'd runtimes, but 
apparently not our favorite one. :D
