   We need to be careful of duplicate names getting into the file list.

   not sure this makes sense with modern mallocs.  At any rate it will

 Hard-link handling
 
   At the moment hardlink handling is very expensive, so it's off by
   default.  It does not need to be so.  
 
+  Since most of the solutions are rather intertwined with the file

   We can rule out hardlinked directories since they will probably
   screw us up in all kinds of ways.  They simply should not be used.
