Not sure what you mean by "reference counted", but yes, if you start
python.exe as a child of some shell such as cmd.exe, then the terminal
that cmd.exe is running in will remain. That is the most normal way to
do things.

Of course, most of us use a shell that's a tad more powerful than
cmd.exe, but the effect is the same regardless.
