Proof by assertion is generally not good argumentation. I'll start a new thread for you to discuss.
More importantly, how is this relevant to this patch?
This patch removes a seldom used function that generates bad code, and MUST NOT be used elsewhere in the code base -- an attractive nuisance, speaking in legal terms.
This patch is also more elegant, and generates faster code.
Are you saying this patch is incorrect in any way?
Please point to the bad line of code (not David's comments or diatribe). Certainly, I'll be happy to correct it!

Yes, I've been involved in many other projects, and am arguably the most widely experienced TCP/IP implementer in the world. I've been programming in C since 1977, and my first TCP/IP implementation was started in 1979 (in assembly). Probably before you were born.
Why are you so threatened by that?
Why are you insulting and trying to drive me away?
Why, oh why, is there such a lack of community spirit here?!?!
