This tests are currently in progress... for the moment, it seems that
the anticipatory io scheduler improves performance a lot.

Couldn't some test be faster inside a container than with a Vanilla? For
example if I want to dump all files in /proc, obviously inside a light
container it will be faster because /proc visibility is limited to the
container session. Just to be clear:

r3-21:~ # find /proc/ | wc -l
4213
r3-21:~ # mcr-execute -j1 -- find /proc/ | wc -l
729

I'm not sure and I'm still investigating. I'm now adding Oprofile to all
tests to have more information. If you know technical reasons that imply
different results, let me know. Help welcome!
