* We'll create server and connect to it using two clients, each writing one |

* When all clients will be accepted by server - we'll start reading from them |

|
* and, on first client's first byte, will close second client and server. |

|
* After that, we'll immediately initiate new connection to server using |
||||
|
* tcp_check handle (thus, reusing fd from second client). |

|
* |

|
* In this situation uv__io_poll()'s event list should still contain read |

|
* event for second client, and, if not cleaned up properly, `tcp_check` will |

|
* receive stale event of second incoming and invoke `connect_cb` with zero |
