Sure, and this is the point.  Pick a number for the RSS and stick to
it.  Crank it up if you don't want to be bothered, but this
"yardstick" can be used to measure trends in the compiler's footprint
by measuring the number of page swaps.  It might also be a way to
measuer/improve the locality of reference since poor locality will
cause thrashing if the RSS is set low enough.  Of course if the RSS is
set too low than *any* pattern of page access will cause thrashing.
