[plt-scheme] tracing procedures defined in module

Hi -

how can I trace a procedure defined inside a module?  Below is an example:

> (require (lib "trace.ss"))
> (require (lib "process.ss"))
> (trace system*)
set!: cannot mutate module-required variable in: system*

I try to keep my own code modular during development, but the limitation
appears to be a hindrance when trace is unable to help me discern what's
going on.  Are there ways to get around this limitation?  I discover this to
be a design choice at http://hkn.eecs.berkeley.edu/~dyoo/plt/modules.text.

Thanks,
yinso
