Will we get two SIGCHLD when two subprocesses exit at the same time, or
only a single one? If they are combined to a single SIGCHLD, maybe
'waitpid' needs to be called in a loop so no subprocess is missed.
Also, I think only the ECHILD system-error and maybe EINTR needs to be
caught here.
Greetings,
Maxime.
