It is a choice, syslog uses datagrams by default so that it may
drop messages and more important, that it doesn't tie the sender
with retries.

So this isn't about reliable transport but only about reporting
transport losses. The ENOBUFS receive error however doesn't solve
this except for the different case of messages on the routing
socket. For the specific implementation of the routing socket this
is apparently the only kind of loss that can happen.

I don't think it's the best solution for the routing socket though,
but it avoids some compatibility problems. For UDP it's useless.
