Hi Kaz,
The 'Unix way' is to have lots of small utilities that do one thing
well, then connect them via pipes. It could be that the optimised sort
algorithm is hampered if it has to remove duplicates too, or that the
maintainers want to draw a line on added functionality.

I figured out the reason. It was because of asyncore.dispatcher's
inefficient implementation of messange sending. Instead of using its
'push' method. I directly call the underlying 'socket.send' and got the
problem solved. Sorry about the spam.
