Bug 801386

Description of problem:
I have executing some performance tests ,and i noticed that for every tests that takes longer then 65 sec output of \usr\bin\time command is that :  USER time is allways less then 65 sec and system time is increase  depend on tests time.

for test period less then <65 sec everything look ok ,but after 65 sec time is starting adding user time to system time .
where mpstat output looks like this for all test time :
 
12:40:17 PM  CPU    %usr   %nice    %sys %iowait    %irq   %soft  %steal  %guest   %idle
12:40:22 PM  all   66.10    0.00    4.20    0.00    0.20    0.00    0.00    0.00   29.5
 

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.start \usr\bin\time [any program that spend most of his time in user mode 
2.wait  120 sec
3.
  
Actual results:

64 sec user time + 56 system time  
Expected results:
119 user time, 1 sec system time
