If you want to learn this, I suggest you start off with something like C
which the kqueue/kevent interface was built for. A Go-idiomatic solution
would usually abstract this away by means of using goroutines[0].

Also, you code seems to be missing part of the usual socket interface.
Calling net.Listen creates a Listener from which you can draw connections
through the means of Accept(). You want the file descriptors of accepted
sockets in your case I think.

In Go, an acceptor pool would usually spawn of goroutines which will then
accept on the socket and do concurrent work. Note that there are many
considerations in building a robust acceptor pool in general (and I would
wager several exist of varying levels of stability).

[0] On Mac and BSD, the interface is usually kqueue/kevent. On Linux a
completely different epoll() interface exist (which is a slightly bonkers
API IMO), and on Illumos you have event ports filling in the same problem

Interestingly, systems such as Node.js is just a wrapper on top of these
eventing systems, to which you've frankensteined in a Javascript JIT on the
side. There are many limitations to such a system with regard to system
stability and latency. Especially as projects grow large.
