As Dave has mentioned, setting SO_SHARE on a socket would be another way
to accomplish this.

Neither of these sounds the same as descriptor passing over Unix
domain sockets on Unix/Linux; the auxiliary server sounds more
like `inetd`, in that there's some service that's listening and
accepting connections on some TCP/IP port, and then creating a
server to handle each incoming connection.

I would claim that what I did is NOT passing a descriptor, or whatever, to another process.  Not really sure what that means.  All I passed was the device name, and let the second process assign a channel to the "existing" device (socket).

SO_SHARE is different again; it appears that the shared socket
must be created before the subprocesses that use it are created.

I don't know why you would say that.  A process must exist before it can do anything, but, a socket can exist in a process, and then connected to in another process, regardless of when the second process is created.  For example, if a bank of worker processes exist, and a task comes in, the connection socket could be opened by the existing selected worker process.
