Hello

It seems that /usr/bin/time program reports a wrong value for MaxRSS.
The report shows MaxRSS, about 4 times the
actual allocated memory by a process and its children. MaxRSS (Maximum
Resident Set Size) is assumed to be maximum
allocated memory by a process and its children. This bug report talks
about this problem. More descriptions are provided in
time-problem.tar.gz file attached to this mail.

Thank you in advance
