 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.
