EOS_PAUSE bug

[GoogleCodeExporter]

On latest master, Ubuntu 14.04.

There appears to be a bug in how Pyglet handles EOS. Using this bit of code 
(where "noise.wav" is just 1 second of noise):

from time import sleep
from pyglet.media import Player, load
noise = load('noise.wav', streaming=False)
x = Player()
x.eos_action = Player.EOS_PAUSE
x.queue(noise)
x.play()
sleep(0.5)
print(x.playing)
x.pause()
x.seek(0)
sleep(0.5)
x.play()

As expected, I get 500 ms noise, an terminal output of "True" (x.playing), 500 
ms silence, then 1000 ms noise. However, if I change the first "sleep" call to 
be 1.5 seconds (i.e., longer than the sound), then I get 1000 ms noise, an 
output of "True" (even though by that point the stream should have been 
paused), and then silence -- the second play() doesn't cause any output. So I 
think somehow "EOS_PAUSE" is not actually effectively calling "x.pause()" (or 
doing the equivalent under the hood) as it should be.

If this makes sense, I can try to take a look at the Pyglet sound code to see 
if I can figure out why this is happening, but that code still confuses me a 
bit...

In case you want the noise sample:

Could it be related to this?

I just commented on that bug -- I can't load the given sample to test it.
