Ensure dumpstate children die
Use prctl(PR_SET_PDEATHSIG, SIGKILL) in each forked child to ensure
it dies when dumpstate dies.
This is important for two cases:
- dumpstate runs a timer for each child process. On expiration, it
sends SIGTERM to kill the process. Sometimes SIGTERM isn't enough
to kill a hung process, so the child lives on.
- When dumpstate is killed by the user before completing, outstanding
children continue to run and generate output.
