Example unix socket echo server

[AJ ONeal]

I believe that I've done this Unix Socket Echo Server "the right way" now:

http://github.com/coolaj86/libev-examples/blob/master/unix-echo.c

The question that I have is if it's true to say that a unix socket is
writable whenever it is readable?

When I tried listening for when it was writable, it seemed to fire the event
over and over again.
I didn't think that was particularly helpful.

Or is it that when I want to send data I should
    start the watcher for writes
    send the data
    stop the watcher
?


Now who wants to change the Unix Socket stuff out for TCP?
I may eventually get around to it, but that's not what I need right now,
interestingly enough.

I'll try my hand at a client now.
