NOTE
Netty Source: Detecting New Connections
How readiness on a listening channel leads the event loop to accept new sockets.
This is a historical learning note and may contain outdated or incomplete understanding.
The listening channel is registered for the transport’s accept/readiness signal. When the event loop processes that readiness, the server channel’s read/accept path drains available accepted connections according to its read policy.
Readiness is a signal that progress may be possible, not an application connection object by itself; transport accept calls still determine what was actually accepted.
Selector event constants and internal dispatch methods vary by version.
