memory management with glibmm & giomm

[nico <nico yojik eu>]

Hi everybody,

Here is a program that list recursively  files from a given directory.
As I understood, Glib unref() my 3 variables at the end of the bloc {}, 
so I don't have to care about that.
But when It run this program, after 2 minutes it use already more than 
80 MB. Is something wrong?
My second question is about the "enumerator->close();" command. Is this 
line mendatory? (It doesn't seems to change anything).
Regards,

Nicolas
