And the latter means that just copying is not good: it is a frequent
case that the child closes one or more of inherited handles that it
doesn't need.  You don't want that to invalidate the handle in the
parent, since existing programs don't expect such a calamity.

Se perhaps writing a (16-bit real-mode) program to test this aspect
would be a useful first step.
