-// TODO:
-//   * Each MidiObject should be added to a static hashtable so we can always
-//     obtain objects that have already been created from the handle, and avoid
-//     having two managed objects referencing the same unmanaged object.
-//
-//     Currently a few lookup functions end up creating objects that might have
-//     already been surfaced (new MidiEndpoint (handle) for example)
