Hi

Apologies if this an obvious mistake. I have a program that I want to 
update the display once every two minutes but I it seems as if any value 
over 1 for the interval in clock.schedule_interval start to consume large 
amounts of memory and CPU. The simplest code I could reproduce this with is 
below.


import pyglet
     
window = pyglet.window.Window()

def update(dt):
pass
@window.event 

def on_draw(): 
window.clear()

if __name__ == '__main__':
    
    pyglet.clock.schedule_interval(update, 10.0)
    pyglet.app.run()

I am running with  Python 3.4.2, pyglet 1.2.4 on OS X 10.10.5

If I set the interval to 0.5 the memory for the process is about 46Mb with 
a very low CPU and it seems to stay at that level.

If I set the interval to 5.0  the memory starts at about 48Mb and within a 
couple of minutes the cpu is moving up to 70% + and the memory is over 
80Mb. It will keep on increasing.

The larger the interval value that I set the faster it seems to increase in 
memory and CPU usage.

Any assistance appreciated
Thanks
