Instead you can manually initialize the jython runtime by calling
PySystemState.initialize(preProperties, postProperties, argv):

- preProperties is useally System.getProperties().
- postProperties can be a java.util.Properties with your own 
  property values.
- argv will be copied to sys.argv

Both registry files (<python.home>/registry & <user.home>/.jython) are
java.util.Properties files.

No.

>Can I reread the registry file?

No. You can't meaningfully modify the sys.registry object either. After
the property files are read (and merged with Properties arguments to
PySystemState.initialize()) the static fields in org.python.core.Options
is initialized. The rest of the jython runtime are looking at these
fields when it needs some configuration information.

They all share the static values of the org.python.core.Options fields.
