PythonEngine.Initialize slow #598

Description

@goerch

Environment

  • Pythonnet version: 2.3.0
  • Python version: 3.6
  • Operating System: Windows 7

Details

When embedding Python in an ASP.NET MVC 5 web application, PythonEngine.Initialize needs a couple of seconds to eagerly load the names of around 50 module namespaces in ModuleObject.LoadNames. If I replace the implementation of LoadNames with a NOP, time spent in PythonEngine.Initialize drops to below 100 ms and the web application still seems to work.
