​Oh, I think I've done something like that too, and there are definitely
still opportunities in Python 3 to ask for the impossible. But what I did
now, I did "on purpose".​ For a split second, I really wanted to know how
bad it would be. But a few minutes later I had little interest left in that
;). Rebooting a computer definitely takes longer than restarting a Python

​To clarify, I was talking about allowing Ctrl-C to break it, which
somebody had suggested. That would also help if the C-implemented iterable
just takes a lot of time to generate the items.

​And for the record, I just tried

>>> sum(itertools.count())

And as we could expect, it does not respect Ctrl-C either.
