[CM] Freeze Running Simplest Examples (snd-ls-0.9.7.12)

[Esben Stien]

Trying again to get snd-ls up and running;). I've now recompiled my
entire OS, but getting the exact same problem;). 

I've compiled snd-ls and started it with M-x run-scheme in emacs. It
starts up fine. I then, in scheme-mode, evaluate (load-from-path
"rt-compiler.scm") and that also seems to go fine. It says RT-Compiler
loaded successfully.

I then run this example code, with C-M-x: 

(let ((osc (make-oscil)))
  (<rt-play> 0 3
     (lambda ()
          (out (* 0.8
                    (oscil osc))))))

At exactly this point, when hitting the combination C-M-x, the snd-ls
GTK window freeze and it's just grey and does not repaint. No sound is
heard.

I'm running jackd-0.102.29 on GNU/Linux-2.6.18-rt7.

Any pointers as to what I can try?
