Memory leak / increase over time

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a standard scene, but use the QuadrantRenderEngine.
2. Add a number of cubes, say 20, in a grid formation of 5x4.
3. Render the scene on an enter_frame bases. Now check the memory by
writing System.totalMemory into a textfield, somewhere on the stage.

What is the expected output? What do you see instead?
Expected is a steady memory usage. Instead, it grows by a small amount each
frame.

What version of the product are you using? On what operating system?
Papervision3D 2.0.0 (March 12th, 2009)

Please provide any additional information below.
I am creating an application that is supposed to run about 12-14 hours, but
if memory keeps increasing, it could cause a problem.

Although GC does its job about every 30 seconds, each cycle leaves a small
part untouched. Without GC, it counts up about 10-100 bytes each frame,
resulting in an average increase of 5-6 kb every minute. After a GC
cleanup, it goes back to where it started before the render, plus a few
tenths of a kb. So after GC, the starting memory has increased by a little.
This means that over a longer period of time, memory will have increased by
a lot.

Example of my app so far:
start: 30kb
after ~30 seconds of render: 33kb
after GC cleanup: 30.1kb
start again, and after ~30 seconds of render: 33.1kb
after GC cleanup: 30.2kb
etc.

Even though this isnt a big issue, because Im talking about an increase of
bytes per minute, I think its still something to be looked at. Especially
when creating apps that are going to run for several hours.

Wael Jammal have written some extends to have pV3D destroyable objects.
But the web site has gone. I have a copy of the code on my local disk.
Please pv3D team provide a dispose() method on your objects.

Garbage collector is not God, it remove objects with no references.
