Hmm.  It didn't work.  (I tried setting it both before and after
instantiating my PythonInterpreter object in Java; didn't work either
way).

Interesting data points:

 * In Python, I printed:
   print Py.getSystemState().getClassLoader().getClass().getName()
   result: com.lutris.classloader.MultiClassLoader
   which is correct.

 * Java still claims that the loader for the base class of my Python
   class is sun.misc.Launcher$AppClassLoader.  I at least have it
   -- through MANY hacks -- showing the correct loader.

 * I just noticed that, somewhere along the line, Java shows the
superclass of my ListBOFoo as being PyFunctionTable.  Eep!  I don't
quite know where that changed from ListBO.  Somewhere in my testing I
guess.  Sigh.

Also:

Is it possible to tell Jython where to create the .class files that it
generates on the fly?
