  It seems a bit silly to me to have topology informations about which
CPUs are part of the same Cell (i.e. share the same memory costs) but
being unable to find out how much memory is actually local to that cell.
Sure the current free heap on that cell helps to place new jobs but it's
only a temporary view.
