I think Mr Jonathan de Boyne Pollard might be cooking, or even already
has, something similar in nosh.
Long since. (-: It was in version 1.0 .
Martin "eto" Misuth:
at some point I was interested in digging out whether systemd had
"subreapers" at it's disposal, and why it didn't use them
It has. The systemd people were responsible for getting this mechanism
into Linux in the first place.

- observing behaviour of reparenting under init for thousands of times
in htop
Now observe it under not init and not htop. (-:
Here's the nosh service manager's subreaper mechanism in action. Process
31427 is a per-user service manager, which is a subreaper. Process 9408
is GNOME Terminal and process 9412 is a Z Shell running connected to
that terminal. In the shell, I ran (sleep 6000&) which resulted in an
orphaned sleep process, process 9451. As you can see, that process has
been reparented to the nearest subreaper.
