I tested the new version with my original (more complicated) program. 
There is no difference between racket and gracket now so this means 
success! :)

OTOH just adding (require racket/gui) to the script adds some overhead 
(a little less than 2x; quite a bit (5x) more mach calls were also 
reported in Activity Monitor). Nothing show-stopping and since the code 
is mostly in Racket now (AFAICT) I may try to investigate it myself a 
little.

Thanks once again!
