 Cleanups:
-o  Clean up introductory comments.
 o  Log messages should show both original and new size of the data. The speed
    should be probably calculated from the former.
 o  Buffer sizing in shep-export.
-o  Problems with thread stack limit in radix-sorting of arrays.
+
+Improvements:
+o  When quicksorting a large input (especially in threaded case), invest more
+   time to picking a good pivot.
+o  Overlay presorter I/O with internal sorting.
