To be fair, keep-alive was not part of the design.  Http was initially 
a completely stateless protocol, and actually a fairly well designed 
one.  The reason keep-alive is not well supported is because it's got 
nothing to do with the original design and was bolted on as an
afterthought. 

Is there a take-home lesson there?  Only that if we engage in elegant 
design we should not trust those who come after us not to screw it up.
