I can do that. However is it really a leak considering the fact that
the program will call exit just after?
If it's a matter of consistency and coding style I would understand
though.

One more thing, git-format-patch added a "From" field to the header and
caused this glitch in the mail. I thought git-send-mail or the mail
server would handle it well but apparently not:

 From 2f5b85fcadcfee3b75a6a21dc86d10b945c99f0f Mon Sep 17 00:00:00 2001
From: Benjamin MARSILI <marsil_b@epitech.eu>

git-am didn't complain with the patch that I sent but it may break after
gmail relayed it 
(http://lists.gnu.org/archive/html/qemu-devel/2011-11/msg03152.html).
The second from header is interpreted as text... Should I remove the
first "From" field before sending the patch?

Sorry for the noise on the ML and thanks to all those who helped me get
involved.
