Ah, does that mean there's a cleaner fix somewhere I should be stealing?

Is there any wisdom in me subtracting a few bytes to account for some memory overhead anywhere?
By the by, I *think* I've gotten to the bottom of my 2046 byte read() buffer
issue (which wasn't tcp_recv_bufsize after all). *If* I am reading this right: HttpStateData::HttpStateData
    readBuf = new MemBuf;

With no arguments, init() will cook up an empty 2048 size buffer, which gets
carried all the way through the OO to the read() call (wherever that is)
that dutifully only reads as much as the buffer says it currently has.

So I'm thinking of hardwiring something in there tomorrow and seeing what explodes.

Ah, by 'broken clients' are we talking IE6 by any chance? :)
