Mono allows third-party profilers to be hooked up. You could modify the
default profiler to do exactly what you described (copy the code, make
the changes, invoke the new profiler code).
There is some information on the SVN man page for Mono, but we could
certainly use a tutorial on the Wiki with more details.
