Oof! I've trusted the accept(2) man page that says:
The accept() argument extracts the first connection request
on the queue of pending connections, creates a new socket with the
same properties of s and allocates a new file descriptor for the
socket.
Apparently, "same properties" does not include TCP_NODELAY!
I will test with [correctly] disabled Nagle on the server side and let you
know the result.
Thanks,
Alex.
