Looks good, but we should add the two different cases as well.

The one that kills the child with SIGHUP should have si_code set to
CLD_KILLED and and the si_status should be SIGHUP. And the 'division by
zero' case is supposed to have it set to CLD_DUMPED. I think that we
should add these two tests as well.

Also looking at man pages the idtype can be set to P_PIDFD since 5.4 as
well, so we should add a waitid test with a pidfd too.
