Opt in only where the trade-offs are acceptable: for up to about 100 ms after the exit, the helper keeps the executable mapped (overwriting the binary in place fails with "text file busy"), its memory stays charged to the cgroup, and the teardown CPU time no longer appears in the parent's resource usage.
