On OSX grace hovers around 1.2 pct of cpu which is total fine, ill test it on linux once i can figure out the crash.

does switching to format stop the crash?


(define (foo)
  (let ((sequence '(0 1 2)))
    (process
      for i from 0 to (length sequence)
      for current-element = (nth sequence i)
      do
      (format #t "~A~%" current-element)
      (wait 1))))

(sprout (foo))
