Definitely a CCL problem.  I have now reproduced it on Linux and using iTerm.

Here is the most reliable demo I have so far:

(defun foo (delay cnt)
  (with-raw-input (dotimes (i cnt) (princ i) (terpri) (sleep delay))))

? (foo 0.1 10)
NIL
? (foo 0.1 10)
0
 1
  2
   3
    4
     5
      6
7
8
9
NIL

It also seems to be sensitive to whether or not there is a character in the input buffer.  Hitting a key while FOO is running changes the behavior dramatically.
