I'm using IronPython as the hosting language... does that mean I just
can't get the extensions?

But in any event, is this workaround:

Yes, all of the hosting code is written in IronPython. When I use the
workaround above, I get tracing but at my IronPython hosting app
level, not at the level of my script being run. The only way I can get
tracing in my Python script being executed, is by having the set_trace
inside that file.

I'm trying to find a way that I can from outside that script (eg, from
the IronPython hosting app) get tracing on. I can probably write some
of this in C# if I need to, but all of the hosting app is written in
IronPython at the moment.
