This is the service supervision approach, which is indeed the best, avoiding race conditions and nasty polling. If you really must monitor processes which you cannot parent, at least under Linux you can do this using ptrace to sort-of-reparent the processes (as long as you have CAP_SYS_PTRACE or your ptrace scope is set to 0 in Yama), with waitpid to monitor all of them. |
