Tomcat 7 may be a candidate. Tomcat 6, If I was an administrator, I would not 
expect any code changes like that in a dot release.

Yes, I'd like to see some real numbers on the request header overhead. I doubt 
it will be an issue for Tomcat 6. For Tomcat 7 large refactorings and 
optimzations are happening all the time, so in there it makes sense.

As I just got back into the code mode of Tomcat, I'll look forward to take a 
look and see how it progresses.
