## Message

```
Io.net: set `receive{,Timeout}` message to `init`

If we use `undefined`, then `netReceive` can `@intCast` the
control slice len to msghdr controllen, which is sometimes `u32`,
even on 64-bit platforms.

`init` just avoids this entirely by setting `control` to an empty
slice rather than undefined.

```
