[issue11299] Allow deepcopying paused generators

[Ram Rachum]

Ram Rachum added the comment:

"Instead of copy.deepcopy, why not call itertools.tee?"

It's hard for me to give you a good answer because I submitted this ticket 2 years ago, and nowadays I don't have personal interest in it anymore.

But, I think `itertools.tee` wouldn't have worked for me, because it just saves the value rather than really duplicating the generator.
