If the directory is not an empty directory, rmdir() shall fail and set 
errno to [EEXIST] or [ENOTEMPTY].

You can always use errno.h if you want to get the last return codes of 
system(-specific) calls! But again, Qt follows the POSIX standard here, 
and so return false in that case is just fine (errno can only be 
ENOTEMPTY in this case).

If you need recursion, simply implement that yourself i.e. by sub-
classing from QDirModel.
