No mem leak detected in Valgrind.

btw, memory_get_usage(1) returns the same value.

Description:
------------
Using stream_socket_client on it's own works fine, but once using
stream_context_create with it it creates a memory leak of 2kb each time
which makes it unstable.

Test script:
---------------
<?php
  for ($i =0 ; $i <30 ; $i++)
  {
    $socket_options = array('socket' => array('bindto' =>
'127.0.0.1:0'));
    $socket_context = stream_context_create($socket_options);

    $fp=stream_socket_client('tcp://127.0.0.1:23', $error, $err, 5,
STREAM_CLIENT_ASYNC_CONNECT|STREAM_CLIENT_CONNECT, $socket_context);

    unset($socket_context);
    unset($socket_options);
    unset ($fp);
    unset ($error);
    unset ($err);clea
    
    echo memory_get_usage()."\n";
  }
?>

Expected result:
----------------
648504
650400
650400
654000
650400
650400
650400

....

Actual result:
