I didn't see GetSysModule for some reason in IronPython 2.7....
perhaps a Mono issue, or maybe I'm not importing it correctly?

But I was able to:

source = engine.CreateScriptSourceFromFile(filename)

However, it ended up tracing the hosting level, rather than the
source. Is that an IronPython issue? Or user error? Is there another
way to inject a trace in an execution?
