anything new on this?

i've managed to reproduce the problem using the examples and iolib
version 5dfec183c4d57fa315d2b29c92d2b90045ea8eed (current head)

i've added some output printing to the client code as seen below.

CL-USER> (in-package :iolib.examples)
EXAMPLES> (make-thread 'run-ex6-server :name "ex6 server")

EXAMPLES> (run-ex5a-client)
Connected to server 127.0.0.1:9999 from my local connection at 127.0.0.1:42670!
alma
Writing to socket: "alma"
Flushing socket
Done

Writing to socket: ""
Flushing socket

alma

Writing to socket: ""
Flushing socket
Done

quit
Writing to socket: "quit"
Flushing socket
Done

happy writing?!
Writing to socket: "happy writing?!"
Flushing socket
Done
quit


and in the inferior lisp buffer i see:

Accepted a client from 127.0.0.1:42670
Creating line-echoer for 127.0.0.1:42670

Client requested quit!
Closing connection to 127.0.0.1:42670

as you can see "happy writing?!" was written into a socket that has
been closed by the server at the previous "quit" line.

i'm not sure it's exactly the same issue as mine, but could be related.
