## [TODO]
### implement the timeout mechanism
**What have I tried?**
- `signal`/`alarm` function inside TCPStream::Recv(char * buffer, size_t len, const
    int wait_time)
    I cannot call `close(sockfd_)` inside the sianal handler fucntion
- use `setsockopt()` to set the socket's `SO_RCVTIMEO` option
    Have to add an additional parameter(`wait_time`) to TCPStream constructor
