I think, nobody doubts that current initsystem is the worst one of
the major linux distributions. By changing paradigm from forking to
non-forking daemon you can avoid all the complicated 'stop' code;
e.g. 'start' will be
| pid = fork();
| if (pid==0) { /* ... */ execve(...); }
and 'stop' be
| kill(pid, SIGTERM); /* wait for timeout/sigchld */ kill(pid, SIGKILL);
But python or other bloaty scripting languages are not a solution and
completely unacceptable at this place.
