[plt-scheme] profiling in MzScheme

For examle. calling the function

(define (flatten x)
   (cond
     [(null? x) '()]
     [(not (pair? (car x)))
            (cons (car x) (flatten (cdr x)))]
     [else
            (append (flatten (car x)) (flatten (cdr x)))]))

by

(flatten '((a b) c))

generates the profile:

% Time      Msec Calls Function
100.000         0       6       flatten


Yes, I am using v209
