[Kinosearch] Sort::External presort and postsort feature

[Ken Clarke]

Thanks for the suggestions and examples.  I'm going to work at trying them 
out, but it may take a bit of work as I see a few problems.  For example, I 
don't see off the top of my head how to support case-sensitive and 
case-insensitive sorting without loosing case during the decoding.  I also 
need to figure out how long to make each encoded block (pack'ed or 
sprintf'ed) so as to ensure it is long enough to sort accurately and decode 
without loss while not placing too great a burden on memory.  This is an 
issue since for my project as there is no way of knowing how many characters 
a given field will contain.

I do have a question though.  Won't the output to temp files of packed 
strings require "binmode"ing the filehandles under Windows?

I'll post some thoughts, results soon.
