There are actually two issues: one is itermittent and is common with
strace-DD.test, namingly, the waiting of the strace's termination is not
done properly, so it checks the actual strace's output too early
sometimes; the other one is the one you've referenced, yes.

Why systemd?  Any process can be child subreaper for whatever reasons.
Yes, it's likely that the solution is to get the subreaper's PID and
check against it instead of checking against hard-coded 1.
