Oh, I thought this was clear by now.  Thanks for letting me know that it
wasn't. :-)

The parent is the process which puts the binary image into the memory and
makes the system call which turns it into a process (called exec() or
similar).  It is in the position to do anything it wants to the child just
before making that system call.  The constructor is simply trusted not to do
anything.

Who pays for the resources is a different question.  Childness is for me
defined by who performs the system call.
