> Suppose that we have 2 childs. The first one is running, the second is zombie

What else would it do?  There is a child that will be reapable eventually
(the running one).  It might be even more strange and more confusing if you
hid the running child just because there is a permission-denied one.  If
you ask specifically for the permission-denied zombie you'll get the
permission error.  I'm not sure we can do better.


Thanks,
Roland
