net.js UNIX domain socket issue

domainsocket.js

var net = require('net');
var path = '/tmp/echo.sock';
var server = net.createServer(function(c) {
    console.log('server connected');
      c.on('end', function() {
            console.log('server disconnected');
              });
        c.write('hello\r\n');
          c.pipe(c);
});
server.listen(path, function() {
    console.log('server bound on %s', path);
});

Damn myself. I saw this issue in v0.7 with my REPLs, but I thought it was me and the REPLs I was working with weren't key to the modules I was writing, so I just commented out that code.

Here are the steps to reproduce:

1. Run the above.
2. (Optionally verify your server works with nc -U /tmp/echo.sock.)
3. Exit.
4. Run again.... Error: listen EADDRINUSE

This issue effects every REPL that's attached to my production code! A workaround for now would be to unlink (remove) the "file":

var net = require('net');
var fs = require('fs');
var path = '/tmp/echo.sock';
fs.stat(path, function (err) {
  if (!err) fs.unlinkSync(path);
  var server = net.createServer(function(c) {
    console.log('server connected');
    c.on('end', function() {
      console.log('server disconnected');
    });
    c.write('hello\r\n');
    c.pipe(c);
  });
  server.listen(path, function() {
    console.log('server bound on %s', path);
  });
});

Here's a nice little optimization from @kitcambridge, removing the stat call and sync:

var net = require('net');
var fs = require('fs');
var path = '/tmp/echo.sock';
fs.unlink(path, function () {
  var server = net.createServer(function(c) {
    console.log('server connected');
    c.on('end', function() {
      console.log('server disconnected');
    });
    c.write('hello\r\n');
    c.pipe(c);
  });
  server.listen(path, function() {
    console.log('server bound on %s', path);
  });
});

And now?
