First can you comfirm me that a files_changed signal can and should
be caught by the directory view between two directory load...

I know the files_added one is used, not sure about files_changed...

But I might have a better fix soon that would avoid making this risky
change... I'll keep you informed...

I observed that when loading a directory, we are losting time in doing
re-layouting even *before* any file get added. 

The reason is the emission of the files_changed signal which trigger
display functions...
