Hi Tran,

I think you've misunderstood the intent of Chet's reply. Nobody 
disagrees that the RSS should not increase. The reason that you're being 
asked for valgrind output is because the problem has yet to be 
reproduced, and the valgrind output might shed some light on where the 
problem lies, since others are not able to reproduce the problem.

Hi Chet,

Thank you for your reply.
I try a very simple script as you can see, I don't think it need to check
by valgrind.
The RSS should not increase for running that script.

The OS used is OpenSUSE 64bit version 12.1
I don't have chance to check on MacOS or RHEL.
