Just in case I retested with pyglet 1.2alpha1, all runs ok here.

Thats... surprising.
Comparing the second and third runs of your script:
the third run explodes in the director.init call
at this point the only difference in app state are the ones created by
the import cocos_particle_systems in the exploding script
and what does that import ? It is equivalent to
from particle import ParticleSystem, Color
from euclid import Point2
because all other code is class definition, so no running at import time.
>From the point of view of side effects at import, thats equivalent
(replacing the first import) to:
import random
import pyglet
from pyglet.gl import *
import math
import copy
import numpy
import ctypes
from cocosnode import CocosNode
from euclid import Point2
forced_point_sprites = None
rand = lambda: random.random() * 2 - 1
All other lines are in class and func definitions, so no running at import
cocosnode.py has no side effects on imports, euclid does nothing openGL,
the last two lines don't change the openGL state.
In fact, the only lines looking as potential culprits to change GL state are
import pyglet
from pyglet.gl import *
I would expect then that my script, the one only involving pyglet, will
crash in the second run.
Yet your results tell otherwise.
And now what ?
I suggest you double check that the second run with my script uncomments
only ONE and that it does not traceback ( yes, yes, just in case)
If the results are the same (no crash) , the only way I can see to
investigate the issue is testing your script gradually commenting out code
in cocos.particle.py and see when it ceases to crash.
As I can not reproduce the issue I cant test by myself, sorry.
