You could make this part of the "load formula".  See sched_conf(5) for
details.  The default is to use the normalized 5-min load ("np_load_avg"),
but you can certainly include other things as well.  However, remeber
that the there are no units, the so an np_load_avg=3.21 will be compared
to the value of mem_free (50465865728, on one of my boxes).  You'll need
to weight the values accordingly...
