Gio & memory management

[nico <nico yojik eu>]

Hello,

I wrote a program that list recursively files from a given directory.
I'm impressed by the memory usage of such a program (after one minutes,
it uses more than 100 BM on my /usr/ directory... after 5 minute I have 
to kill the process : I've only 512 MB of RAM... so my system is 
becoming unstable).
(for comparison, the same program written in php uses less than 1 MB to
list all files of my /usr/).

Is something wrong in my code? Do I forgot to unref or free something?

Regards,
Nicolas
