callback did not fire if get/set connection timeout

[Pridesama]

to test memcached locally, i use below configurations

{
    poolSize: 1,
    timeout: 1,
    retries: 0,
    retry: 100,
    debug: true
}

since the timeout has been set to 1ms, i can see calls of set/get hangup frequently.

memcached.get(key, function (err, data) {
     // the hangup call missed callback
});

there's only query command like "get xxx" been printed but not the response and END mark. the problem occurs less if enlarge the timeout.

set timeout to 1 might be stupid but i hope someone can explain to me why this may cause command execution no response?

by the way https://github.com/3rd-Eden/node-memcached/blob/master/lib/memcached.js#L310-L315

this.connect(server, function allocateMemcachedConnection(error, S) {
      if (memcached.debug) {
        query.command.split(LINEBREAK).forEach(function errors(line) {
          console.log(S.streamID 

the S might be undefined here if error happened
