[Python.NET] Cannot initialize OLE

[Brian Lloyd]

This probably has to do with the threading model being auto-magically
set for you when the CLR is cranked up, absent any prior initialization.

The managed version of python.exe is able to set the threading model
(to MTA I believe) because it is a managed executable. When you import
clr via the standard python.exe, you are probably getting the default
model (STA). I could have those backwards - its been a while ;)

If you are using the win32com extensions, you might be able to import
those, set the threading model for the process, then import clr. Not
sure if that will work, but its worth a shot. I don't think there is
any way to change the threading model once it's set.
