Unlike the C IDL code, the Python version still monitors the _Server DB with "monitor" instead of "monitor_cond". This results in receiving an entire Database row every time the "index" value is updated which includes the 'schema' column. Using "monitor_cond" will result in "update2" notifications which just include the changed "index" value. Unlike the C IDL, the Python IDL requires a SchemaHelper object to instantiate the IDL, leaving it to the user of the library to call "get_schema" themselves. Since the Python IDL did not have support for retrieving the schema automatically and did not have a state for doing so, instead of transitioning on an error response from retrieving the _Server schema to requesting the "data" schema, this moves directly to monitoring the "data" DB.
