does server.on('close') happen after all streams have closed? or when you call close

server.js

var net = require('net')

var port = 89899

var streams = 0
var server = net.createServer(function (stream) {
  var i = 0
  var int = setInterval(function () {
    stream.write( i++ + '\n')
    if(i > 5) {
      stream.end()
      clearInterval(int)
    }
  }, 1000)
  streams ++

  stream.on('close', function () {
    streams --
    if(streams === 0)
      server.emit('quiet')
  })
}).listen(port, function () {
  console.log('CONNECT')
  net.connect(port).on('data',console.log)
})

setTimeout(function () {
  console.log('please close')
  server.close(function () {
    console.log('CLOSE')
  })
}, 1000)

server.on('quiet', function () {
  console.log('QUIET')
})
