This is Go std lib stuff. Nothing fancy... Only thing I can think of is UDP OOB tracking: https://github.com/miekg/dns/blob/master/udp_linux.go

Ack. Was wondering about that.
But don’t I always need a syscall at some point to read data of the network? I.e. what makes this special?

Ok. But this is just 1 goroutine per UDP connect. So one 1 ready \(and write\) for each UDP conn. I.e. is this buggy std lib or me?
