Yes, saw that in the svn logs, and I agree with it.

I had the same thought, so I took the request as captured with the 
packet grabber and tried it against zope using telnet, and it produces 
the required result. That in itself is perhaps a hint, I think the 
telnet client inserts the correct CRLF sequences which might not be 
immediately apparent.

Also, if read(2) returns zero it means EOF, so the problem must somehow 
be on the backend. I'll reply again on this thread if I manage to figure 
it out.
