How to cleanup (purge) a socket connection object?

@allObjects

my.socket:

={ "type": 0, 
  "#onconnect": function (e) { ... }, 
  "opt": { 
    "host": "example.com", 
    "port": 1234 }, 
  "sckt": 18, "conn": true, 
  "#ondata": function (e) { ... }, 
  "#onerror": function () { ... }, 
  "#onclose": function () { ... }, 
  "#onend": function () { ... }, 
  "dSnd": "", 
  "dRcv": undefined }

my.socket.write("hehe") actually sends "hehe" to the server.

my.socket.close():

>my.socket.close()
Uncaught Error: Function "close" not found!
 at line 1 col 11
my.socket.close()
            ^

But, Socket.end() seems to work as expected, with an acceptable delay.
