[cmucl-imp] Working set

[Helmut Eller]

Is there an easy way to determine the working set size (resident size)
that is needed to evaluate some form?  

TIME prints various things but not what I need.  The Linux top command
shows a column with the resident size; essentially I'd like to see
the maximum of the those values sampled while executing the form.

Does the GC have this information already?  Would it be
difficult/expensive to use getrusage in GC hooks to collect the
information?
