…rs in `pyexpat` (python#139403) * Modules/pyexpat.c: Disallow collection of in-use parent parsers. Within libexpat, a parser created via `XML_ExternalEntityParserCreate` is relying on its parent parser throughout its entire lifetime. Prior to this fix, is was possible for the parent parser to be garbage-collected too early. (cherry picked from commit 6edb2dd)
