After the clients quit, the session kept Darling running: Riot and League
crash handlers never exit under Darling, and the idle check counted them as
clients. Ctrl+C or closing the terminal killed bubblewrap, whose
--die-with-parent then killed nix-lifecycle.py before it could shut Darling
down, which left a live server marker behind.
- nix-idle.py ignores crash handlers when deciding whether a client still
uses the prefix.
- The launcher starts bubblewrap with INT, QUIT, HUP and TERM ignored, and
env restores them inside. The supervisor turns them into a stop request.
- nix-lifecycle.py polls for a signal or stop request and then shuts Darling
down without waiting for clients. It stops retrying a failed shutdown once
the server is gone, and waits for or kills its own command afterwards.
- darling-lol --stop makes the stop request and waits for the session. If
the session does not exit within 30 seconds, or no session holds the lock,
it kills the prefix's darlingserver and launchd like darling shutdown,
after checking that the marker PID is this user's darlingserver for this
prefix.
