[Ironpython-users] Differences with pyc-compiled assemblies?

I've added it at http://ironpython.codeplex.com/workitem/33341
The formatting is screwed up now because I didn't relies it wouldn't preserve any spacing (even returns!). I'm trying to fix it up, but the site seems very slow at the moment - about a minute between any requests to the site.
For now, importing directly seems to work, or I'll play around with removing the call/warning to see if that works - it's only a deprecation.
