Yes, that would be the correct and general solution (I hope you get to
fix it, else I may look into it in some time).  Workarounds currently in
use can be seen in our mutter package definition (it's a bit convoluted,
having to fork a process in which we set the child reaping property and
invoke the test suite via tini, acting as a fake PID 1).
