  if i add up erlang:system_info(allocated_areas), total heap memory 
([process_info(P,memory)||P<-processes()]) and total ets memory 
([ets:info(T,memory)||T<-ets:all()]) i get between 99% and 0% of what the os 
reports, depending on the history of the node. i would expect that the "holes" 
of matthias accounts for much (all?) of the rest. what do you get if you do 
that addition, matthias?
  we have tried many different mallocs, none has been outstanding.
