Then I save this application on Mac OS X with save-application, prepending the kernel and producing a neat self-contained application bundle that can be runned by double clicking on it (I’m planning a future version for Windows and Linux).

I tried to different strategies inside this function: opened a socket with an “accept-connection” on it to terminate when a connection is done to the socket port, or perform a (read) (which does not return since the application does not read anything).

Are you making a Cocoa-based application? If so, there are a couple of Info.plist keys that might be helpful.

One is LSUIElement.  If this is true, then the app won't show in the dock, although the app can still come to the foreground and show a user interface.

The other is LSBackgroundOnly. This is used when you want to make a faceless background app.

If you are not using a Cocoa-based app, then I'm not too sure.  In order to make something double-clickable, I think you generally need to have it in an app bundle structure.

Some brief googling turns up https://github.com/subtleGradient/tilde-bin/blob/master/appify

This is a shell script that will create a minimal app bundle for a given program.  Maybe reading that will give you some ideas.
