No dispose functions, unable to destroy particle system

[Lyve1981]

There is no dispose function for the EffectGroup or any other of the classes.

The result is, that when I spawn a particle system multiple times and then remove it, after some time I get a flash exception "Vertex Buffer Resource Limit exceeded".

It should be auto recycled by the GC system. And it work well in my program.
Could you give me a simple example to reproduce it?
