Review comment:
The idea was to force the execution of a exit(EXIT_SUCCESS) instead of
exiting with error code (last line if normal flow).
POSIX exit() terminates the task, closes all fds, etc. I think it is safer.
I can remove the if(...) { ... }, but the not the exit(EXIT_SUCCESS) given
it was correctly terminated by a SIGTERM at that point.
