No, I really mean the OnExitInstance of the app, since that is the override you would have
to write. You cannot write CWinThread::ExitInstance, because that function is already
defined by the MFC library.

atexit seems a quaint hangover from the days of the PDP-11. I generally try to ignore its
existence.

It is not clear why an intermediary process needs to be created to create a new instance,
as one reply suggested.
