For some reason = worked here, I haven't delved further into it.
The named let suggestion was also good thanks.
In the end it turned out I also needed a mutex to synchronize output, so
now I have both a mutex and an atomic for the same thing(a console
progress indicator), which is kind of redundant I guess.
Anyway, I learned new things about guile, so thanks again!

I wound up with this, is there some better way to do this? Feels a bit verbose.
(define (incatom atom)
(let ((expected (atomic-box-ref atom)))
(while (not (= expected (atomic-box-compare-and-swap! atom expected (+ 1
expected
(set! expected (atomic-box-ref atom)

I expected to be able to do the following:

es atomics?
I think I expected to be able to do the following:

I think the slowness was during lisp compilation, and that didnt use to
benefit from parallel compilation. I might try again though.

me, much more than a normal emacs
./autogen.sh && ./configure && make
The build took 53 minutes including the time to clone the first time.
The second time took only a couple of minutes. This was on a fairly
beefy machine.
m-x tetris, and m-x zone worked fine!

tried different ways to interface to Clutter from Guile. I
hacked guile-clutter until it compiled but then it didn't want to
runtime link. I tried Sbank, but it didn't work with guile. I also tried
guile-gir, but it didn't work too well either. So until any of these
other approaches pan out I can embedd guile.
