tsk tsk tsk :) If the "body" of the POST is < MSS it really aught to
be sent along with the headers. (I know, I know, volunteers are
always welcome - i'm just not to that part of using libcurl yet for my
bencmark - the harness has to be finished first :)
 
More generally, if the last chunk of the POST body is < MSS, it should
be sent with the previous chunk (which may be the POST headers).
 
So long as any one send is larger than MSS (or there is only one send
when < MSS :), the Nagle Algorithm will not be a problem on any stack
where Nagle is implemented correctly.
