ofThread consumes 100% CPU usage

Hi, I'm trying to use ofThread but it is really expensive just for using the empty while loop in the threaded function.

Here's my code.

Everything in ofApp.h and nothing in ofApp.cpp

#pragma once

#include "ofMain.h"

class myThread : public ofThread {

public:

    myThread(){

        startThread();
    }
    ~myThread(){

        stopThread();
    }

private:

    void threadedFunction()
    {
        while (isThreadRunning()) {

        }
    }
};

class ofApp : public ofBaseApp{
	public:
		void setup();
		void update();
		void draw();

		void keyPressed(int key);
		void keyReleased(int key);
		void mouseMoved(int x, int y);
		void mouseDragged(int x, int y, int button);
		void mousePressed(int x, int y, int button);
		void mouseReleased(int x, int y, int button);
		void mouseEntered(int x, int y);
		void mouseExited(int x, int y);
		void windowResized(int w, int h);
		void dragEvent(ofDragInfo dragInfo);
		void gotMessage(ofMessage msg);

    myThread thread;
};

When I run this code, the CPU is over 100%.
Is it normal? I'm using OF v0.9.8 on Mac OS X 10.11.6.
Any advise or guidance would be greatly appreciated!
