Just in case someone finds this memory leak:
-1 means big trouble (at the moment no memory left),
I don't bother with further cleanup because if one gets to
this point he will have more problems than a few memory
leaks and because one 'dir_list_clean' would not be enough (and
because I don't want to spent the time to make it working,
IMHO it's not worthwhile).
