No problems. Here's the patch without the extra @node updates.
I haven't signed any papers with the FSF so if the patch is considered
too big to incorporate without signing copyright papers then I'd be
happy to.
* posix.texi: Added more examples of usage and a sample TCP/IP
client/server.

+port 2904 for incoming connections and sends a greeting back to the
+client.

+ (setsockopt s SOL_SOCKET SO_REUSEADDR 1)
+ ;; Specific address?
