-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 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  Log messages should show both original and new size of the data. The speed
    should be probably calculated from the former.

-o  Automatically tune ASORT_MIN_RADIX, ASORT_MIN_SHIFT and especially ASORT_RADIX_BITS.
-o  Check undefs in sorter.h and array.h.
+o  Buffer sizing in shep-export.

 
 Improvements:
 
 Improvements:

-o  Switching between direct and normal I/O. Should use normal I/O if the input is small enough.
-o  How does the speed of radix splitting decrease with increasing number of hash bits?
-   Does it help to use more bits than we need, so that we sort less data in memory?
-o  Add automatic joining to the custom presorter interface?
+o  When quicksorting a large input (especially in threaded case), invest more
+   time to picking a good pivot.
