I was trying to add a GUI windows to my small Racket program for

Can you try the current GRacket 2 prototype?:
http://github.com/mflatt/gr2
On my Mac OS X machine, I see the same doubling of CPU use that you see
when using the current GRacket, but GRacket 2 behaves like plain
`racket'.
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!
