On second thought, please forget my patch.  get_child_status will abort
anyway, if the bug that I hypothesized occurs, so my patch isn't needed.

That could well work, yes, and it might be worth trying if we see
the right symptoms.  But since get_child_status is not aborting I
don't think we're seeing the right symptoms.
