[gambit-list] limiting trace

Code:
~/code/irc$ cat trace.scm
(define (foo x) x)
(define (bar) (foo 0))
(define (test)
(foo 1)
(bar))
(trace foo)
(test)
~/code/irc$ gsi trace.scm
| > (foo 1)
| 1
| > (foo 0)
| 0
Problem:
Can I control trace where I can say "trace foo, but not when it's called by
bar".
I.e. rather than just saying "trace this function", I would like to be able
to say:
(trace foo predicate)
where predicate is a function that takes as input the "stack" frame, and as
output creates a #t / #f, which decides whether this particular trace should
be printed
On a side note -- all the cool debugging functions in Gambit -- is this part
of the 100K LOC scheme or 50K LOC hand written C? (hoping it's the former)
