Then it is not a zombie. Zombies are exited processes which still have their
parent, but the parent has not (yet) collected their exit status.

There's no point trying to kill a zombie - it has already exited and is
using no resources other than a process table slot to preserve the PID
against reuse until the parent has waited, and to hold the exit status
the parent will collect.

In the cited case, the process hasn't exited, so it is not a zombie anyway.
