freebsd4.11 patch for nfs over tcp

[Jim Rees]

I see by inspecting the code that you are right and the web site I consulted
was wrong.  Don't believe everything you read on the web.

I also see that Nagle himself suggests not using his algorithm with delayed
acks.  It can work, but all the timers have to be just right.

Anyway this bug was fixed a while ago, and I don't think there will be
another 4.x kernel, so there's not much to be done about this.
