This is not related to multi-threading, there is one single interaction.
Either NormalInelasticity etc is broken, or ScGeon6D is. Jerome, you
will have to go deeper to find out about the differences.

You might also have a look at scripts/test/compare-identical.py (_you
will need to adjust it perhaps_) which runs the same simulation twice
and checks that it is identical.

Bug description:
Launching scripts/normalInelasticity-test.py., with r2535, I get random results (two different ones) if I launch this script few times successivly (quitting Yade after the end of each launch)
It is about two spheres in contact, which move relatively to each other, and (at the end of the script), especially rotate relatively to each other.

The last figure displayed by the script, which represents the evolving torque contact, is random : I can get two different figures, which are attached.
