Hmph, is this safe to do? Who is feeding child_out? Aren't they
get upset if we do not slurp what they write to us? Are we
expecting to read more from them after this part? Aren't we get
upset if we leave some other stuff when we read from child_out after
we saw "get"? If we respond to child_in without reading all from
them, do we not get into a deadlock?
Perhaps these are all silly questions, but the description above
does not quite answer them.
