We are working on a plugin to use ODE (Open dynamics Engine) in Squeak 
environment. It seems to work but when we want to test it on a real example 
with Balloon3D, we can start our test just once in 1024*768 and after the 
memory seems tu be full.
When we try in 640*480 we can only start our test 3 times and the same 
problem happens : it became very slow and we obtain the crash of Squeak with 
a "Segmentation Fault". 

PS :  We're using a 3.4 VM with a 3.5 image under a Debian Linux. 

Please help us managed the memory with Balloon3D because we really need some 
help to achieve our long work ...
