-Testing:
-o  Giant runs.
-o  Records of odd lengths.
-o  Empty files.
-
 Cleanups:
-o  Clean up data types and make sure they cannot overflow. (size_t vs. u64 vs. sh_off_t vs. uns)
-o  Clean up log levels.
-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.
