[issue19829] _pyio.BufferedReader and _pyio.TextIOWrapper destructor don't emit ResourceWarning if the file is not closed

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I don't like _dealloc_warn() at all. It looks as a dirty hack and doesn't work with custom file-like objects.

I think we should use one of Martin's option. If there are any issues with garbage collecting, we should fix the garbage collector.
