I have committed a patch that shows maxrss, with /1024 adjustment for
macOS.  That should cover all platforms that I could find.(*)

I omitted the i{x,d,s}rss stuff.  My understanding is that to show them
you should divide the numbers by the elapsed time in some specific way.
Seeing that neither Linux or macOS fill these numbers in, I lost
interest.  Someone could produce a separate patch to address this.

Since you were only interested in maxrss to begin with, I think this
thread is concluded.(*)

(*) modulo buildfarm wrath
