So here's the things to consider:
  * Do not preallocate a read buffer per socket.
    Either use polling or use a shared buffer pool.
  * Avoid statefulnews, e.g:
    - In windows, you can't use multiple completion ports with a handle.
    - On unix, a socket is either in blocking or non-blocking mode
    This creates problems when you want to share a handle with other processes
    or between threads. For example, you might want to switch stdout to
    non-blocking, but if stdout was inherited and shared with the parent
    process, the parent process might not expect this and crash or malfunction.
