Testing your code sample on OS X (10.13.6) with Python 3.6.2:
- quit() in the console yields
Exc 0: closed is True

- ^D and raise SystemExit in console both yield:

Try 1: closed is False
So it looks like the issue is specific to quit(), as you say. I'm not sure I
understand what the purpose of the sys.stdin.close() call is, though: why would
we *want* to alert the parent shell in some way beyond a SystemExit as the
default (non-overrideable) behavior? This may be a documentation issue, but it
seems extremely surprising to me; no other function does this additional thing,
even when raising a SystemExit. I would think that any caller which is running
InteractiveConsole.interact() and also wants to do something when it finishes
would want to handle that additional logic itself.
