On Debian stable, getrusage(2) sas:

       ru_maxrss (since Linux 2.6.32)
              This is the maximum resident set size used (in kilobytes).  For
              RUSAGE_CHILDREN, this is the resident set size of the largest
              child, not the maximum resident set size of the process tree.
