Objects with a 500,000+ character __repr__ will cause the IDLE shell to hang and thus lose any progress on open windows. 200,000 (on a decent system) seems to be the tipping point where it can never recover.

I am quite aware that tk text widgets (and probably other widgets) have line-length limitations.  Which issue this duplicates depends on what action you propose.  #28840 proposes addressing limits in the docs. #1442493 is about code changes.
