Eu pareço estar tendo o mesmo problema que este cavalheiro:SensorEventListener não é cancelado com o método unregisterListener ()

public void onCreate(Bundle bundle) {
            super.onCreate(bundle);
            ...
            loopThread();
}

private void loopThread() {
            boolean found = kill;
            System.out.println("Looping until Found!");
            locationThread = new Thread(){
                    private float myacc;

                    @Override
                    @Override
                    public void run() {

                            while (found == false && !kill){
                                    System.out.println("Another Loop!");
                                    getMyLoc();
                                    found = isFound(mylat,mylng,target_lat,target_lng,radius);
                                    try {
                                            synchronized(locationThread){
                                                    locationThread.wait(100);
                                            }

                                    } catch (InterruptedException e) {
                                            // TODO Auto-generated catch block
                                            e.printStackTrace();
                                    }
                            }
                            mSensorManager.unregisterListener(senslistener, mAccelerometer);
                            mSensorManager.unregisterListener(senslistener, mGravitometer);
                            mSensorManager.unregisterListener(senslistener);
                            locationThread.interrupt();
                    }
}

@Override
    public void onPause(){
            super.onPause();
            mSensorManager.unregisterListener(senslistener, mAccelerometer);
            mSensorManager.unregisterListener(senslistener, mGravitometer);
            locationThread.interrupt();
    }
    @Override
    public void onResume(){
            super.onResume();
            senslistener = new mySensorEventListener();
            mSensorManager.registerListener(senslistener, mAccelerometer,     SensorManager.SENSOR_DELAY_NORMAL);
            mSensorManager.registerListener(senslistener, mGravitometer, SensorManager.SENSOR_DELAY_NORMAL);
            if (true)
                    loopThread();
    }

private void registerSensors() {
            mSensorManager =     (SensorManager)context.getSystemService(Context.SENSOR_SERVICE);
            List<Sensor> mySensors = mSensorManager.getSensorList(Sensor.TYPE_ORIENTATION);
            if(mySensors.size() > 0){
                    mAccelerometer =     mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
                    mGravitometer =     mSensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD);

                    mSensorManager.registerListener(senslistener, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);
                    mSensorManager.registerListener(senslistener, mGravitometer, SensorManager.SENSOR_DELAY_NORMAL);
                    Toast.makeText(context, "Getting your location...", Toast.LENGTH_LONG).show();
            }
            else{
                    Toast.makeText(context, "No ORIENTATION Sensor", Toast.LENGTH_LONG).show();
            }
    }


public boolean onKeyDown(int keyCode, KeyEvent event) {
            if (keyCode == KeyEvent.KEYCODE_BACK) {
                    Intent i = new Intent(this, MFLMain.class);
                    if (locationThread != null)
                            if(locationThread.isAlive()){

                    mSensorManager.unregisterListener(senslistener, mAccelerometer);
                    mSensorManager.unregisterListener(senslistener, mGravitometer);
                    mSensorManager.unregisterListener(senslistener);
                    locationThread.interrupt();
                            }
                    locator.stopListener();
                    kill = true;
                    System.out.println("Kill the app "+kill);
                    finish();
                    startActivity(i);
                    return false;
            }
            return super.onKeyDown(keyCode, event);
    }

Quando eu bati de volta para esconder o aplicativo e matar a atividade, ainda recebo o system.out no logcat. A cabeça desiste, como evidenciado pela falta de sistema. Estou muito confuso e não acho que o escopo seja o problema, pois o gerenciador de sensor está sendo instanciado através de um método init e em nenhum outro lugar.
