+File list structure in memory
+
+  Rather than one big array, perhaps have a tree in memory mirroring
+  the directory tree.  
+
+  This might make sorting much faster!  (I'm not sure it's a big CPU
+  problem, mind you.)  
+
+  It might also reduce memory use in storing repeated directory names
+  -- again I'm not sure this is a problem.

+Handling duplicate names

   We need to be careful of duplicate names getting into the file list.
   See clean_flist().  This could happen if multiple arguments include
   the same file.  Bad.

 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
