Could you tell me more about the real use case behind such a set-up.

These children become zombies, and then what will be done to the container that lost the "git" process, running of which presumably was the primary reason why the container was brought up in the first place? Wouldn't these zombies go away when the container that finished its sole purpose of running "git" gets dismantled?

Thanks.
