Or, the default servlet could check if the response is instanceof non-blocking 
response and supply it with the appropriate file channel for response body; the 
response would take care of instructing the connector to transfer the file using the 
direct filesystem cache-to-socket transferTo() method in its own non-blocking code. 
This way, the majority of the logic would be inside a connector; the servlet would 
only have few lines of additional code inside an
if(resp instanceof ...) block

I believe someone on this list once said something like "open source development: have 
fun or get paid for it". I'm working on NIO solely because it's a fun new technology 
in Java with a huge potential, and if it happens to turn out useful it's a clear win.
