It seems to be something which is GC releated. even if I have never
seen the behaviour you describe, my experience is that "when it weird,
it's the GC". I really don't like what you have describe
above. Perhaps to be sure that this is the GC, you could try to
change the number of nitials cells to a very big number and to very
little one and see if you have a difference. Tell me what it gives.
