[Python.NET] import clr causes windows service script to fail

[msutton]

Import clr causes windows service script to fail.
Windows Service script is for Pyramid:
https://github.com/Pylons/pyramid_cookbook/blob/master/deployment/windows.rst
Without WS script, "import clr" from python works.
Without "import clr", WS script works.
Together they fail. Setting "import clr" in script, the Windows Service 
will install but won't start. Setting "import clr" in any of the Pyramid 
views and the Pyramid application fails when the view is called.
