After noticing in swank-ecl.lisp:

(defun make-socket-io-stream (socket)
  (sb-bsd-sockets:socket-make-stream socket
                                     :output t
                                     :input t
                                     :element-type 'base-char))

And seeing via a code audit that the ECL implementation unlike SBCL's
expected :buffering-type with a nil default (no buffering), the stream
is obviously non-buffered...  But I have a patch to make
contrib/socket.lisp more compatible to sb-bsd-sockets in this reguard
(which uses :buffering key with a default of :full).  I'll try to
submit it via the sourceforge bug tracking system soon.

Thanks,
