## Message

```
std.Io.Threaded: optimize batchAwaitConcurrent for net_receive

Eagerly receive messages with MSG_DONTWAIT before polling. This makes
the DNS resolution use case end up doing:

recvmsg (EAGAIN)
poll
recvmsg (success)
recvmsg (success)

rather than:

poll
recvmsg (success)
poll
recvmsg (success)

```
