tail is not the same as tail -f, and /usr/bin/od (and /usr/bin/hexdump) 
end execution when they reach the end of a regular file, such that 
piping into tail (with or without -f) would be useless.

Feel free to write the patch. There is a 12% time improvement to gain 
with splice(2), at least there is here when testing on a 2GB file.
