Comment:
This is not a bug - Handles have buffers, so when you use `hWaitForInput`,
the input is read into the buffer. The `recv` function doesn't read from
the `Handle`, so it doesn't see the data in the buffer. The rule of thumb
is that if you turn a socket into a `Handle`, you should use the `Handle`
operations for reading and writing from then on.
