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.
