I disagree. The OP emphasized the _most_ cost efficient way. In terms  
of both CPU time _and_ developer time efficiency, my method reigns  
supreme. I learned this valuable lesson while at Gemstone. They used  
unix sort for certain types of sorts (esp for large data) because you  
can't beat a 20+ year old tool, so why reinvent the wheel?
