Would it make sense to limit write attempts here? Could execution get stuck here when unable to write?

Yeah, I also thought on adding a limit but;

If we end up in a position where we could not write anything on a socket, it most probably points a resource starvation on the computer either cpu or network buffers related. In either case the problem lies somewhere else and if we throw some exception here - where theoretically it is not an error - we would break the runtime and eventually become a point of failure.

We also loop on the same condition at line on the same method, so I thought this would also not be a problem.

Does it make sense?

I found this argument is fair.

Makes sense, and if socket is completely broken exception will be thrown by #channelWrite () method.
