[IronPython] Access to current Python engine in C# (Silverlight)

[William Reade]

I had a similar problem in Ironclad -- needing to get the engine which 
called a C# method. Try adding a CodeContext parameter to GetModule 
(which gets automagically inserted; no need to change the call from 
Python), and then using PythonContext.GetContext to get a PythonContext 
from the CodeContext. See the constructors in 
http://code.google.com/p/ironclad/source/browse/trunk/src/Python25Mapper.cs

...if your goggles can stand it.
