## Message

```
std.Io.Threaded.netReceive: recvmsg first, then poll

Calling recvmsg first means no poll syscall needed when messages are
already in the operating system queue. Empirically, this happens when
repeating a DNS query that has been already been made recently. In such
case, poll() is never called!
