  • Implement full GC protocol support for _csv heap types
  • Use tp_clear iso. tp_finalize to clear type contexts

Petr's reproducer now outputs the following:

$ ./python.exe bug.py 73166 73168 73168 73168 73168 73168 73166 73168 73168 73168

However, the _csv test suite now leaks (EDIT: updated output after b8772d6)
UPDATE: No leaks after 19e2952

(I'm applying skip news to this, @pablogsal (@corona10), as it is similar to GH-26072.)

One thing that I don't understand is why the CSV tests when executed under the refleak checker don't show any problems
