I think that is not relevant, since 1. yade parallellizes very badly in 
general (seriously), 2. the other loop would skip that body immediately; 
since openmp distributes load in chunks, then each thread usually works 
on id-wise distant bodies, while clumps have ids typically adjacent 
(with O.bodies.appendClumped).

Anyway, I factored away that function so that there is just one loop now.
