[iolib-devel] Bug when using READ-LINE on non-blocking fds

Hi,

Iolib behaves in the following way when using READ-LINE with a non-blocking fd:

;; *client-stream is the stream associated with a client connected to our server

IRCD> *client-stream #<active IPv6 stream socket connected to ::ffff:127.0.0.1/41460 {1004D5D451}>

IRCD> (fd-non-blocking *) T

;; client sends the string "foo" down the socket, no newline is sent

IRCD> (ignore-errors (read-line *client-stream)) NIL #<System-Error EWOULDBLOCK(11) "Resource temporarily unavailable">

;; client sends the string "bar", followed by a newline

IRCD> (ignore-errors (read-line *client-stream)) "bar" NIL

So, essentially, the string "foo" is lost. Shouldn't the correct behaviour be to wait till a newline arrives on the socket?
