Welcome to Armed Bear Common Lisp (and Common Lisp in general)!
I've a socket stream named "socket" in this port and host: 50362 and

Maybe the underlying stream wants to optimize the socket writes and keeps
your write buffered for now? In that case, you want to use FORCE-OUTPUT to
make sure all internal buffers get written to the stream.
Hope that helps!
