 // BluetoothSocket represents a socket to a specific service on a
 // BluetoothDevice.  BluetoothSocket objects are ref counted and may outlive
 // both the BluetoothDevice and BluetoothAdapter that were involved in their
 // creation.  In terms of threading, platform specific implementations may
 // differ slightly, but platform independent consumers must guarantee calling
 // various instance methods on the same thread as the thread used at
 // construction time -- platform specific implementation are responsible for
 // marshalling calls to a different thread if required.
