The installer runs the engine as <venv>\Scripts\python.exe, and since Python 3.7.2 that file is a redirector that spawns the real interpreter as a child. Stop() terminated the redirector and left the interpreter - the process holding the cameras and the SQLite WAL - running with no parent and nothing able to stop it. Seen on a Windows install: Quit from the tray, and recognition still running. The child is now started suspended, placed in a job object with KILL_ON_JOB_CLOSE, and resumed. Cancel terminates the job, so the whole tree goes; and the job dies with this process, so it goes even if the app crashes. CREATE_NO_WINDOW while here: python.exe is a console program and a GUI parent otherwise opens a black console on the shop counter.
