[issue23691] re.finditer iterator is not reentrant, but doesn't protect against nested calls to __next__

New submission from Evgeny Kapun: Iterator returned by re.finditer includes a SRE_STATE value, which is not designed to be used concurrently. However, it is possible to call __next__ on such iterator while another such call is in progress, e.g. from a signal handler. This may result in
