What steps will reproduce the problem?

What is the expected output? What do you see instead?
At firest,the process takes up 14M memory.After watching Youtube for about 2 
hours,it eats 96M.

What version of the product are you using? On what operating system?
os: Archlinux + Xfce4.10 + Chromium
- python2 2.7.3-4

Better,but still the same that only taking up memory from 14M+ to 60M+ slowly 
in 3 hours browsing.Why don't recover the memory?BTW,APPP always uses about 15M 
memory.

I think the problem is PYOPENSLL/OPENSSL:

- http://journal.paul.querna.org/articles/2011/04/05/openssl-memory-use/

Do you have any ideas?

Sorry,I'm just an end-user,know little ABC programming.
The test version seems better as leaving the process idle for a long time it 
releases memory from 60M+ to 24M+,but keep using,it only keeps increasing.

Maybe memory fragmentation?

It could be normal because of memory fragmentation (and the way the python VM 
works).
