Note that we still have to block SIGCHLD so that we can be certain the process is not reaped before we get the pidfd to it. safe_fork() and friends are used in libsystemd where we don't control how the SIGCHLD signal is configured. Specifically, kernel autoreaping could be enabled which is why we have to block SIGCHLD until we get the pidfd so that the kernel cannot autoreap the process before we get the pidfd.
