+Subject: [PATCH] Keep the refusing-dict fixture counting popitem on Python
+ 3.15
+
+bidict_refusing_nth_write() builds a backing mapping that refuses its nth
+write, by counting the writes that pass through __setitem__ and __delitem__.
+That relied on UserDict routing every removal through __delitem__, which held
+until Python 3.15 gave UserDict a popitem() of its own that goes straight to
+self.data. On 3.15, MutableBidict.popitem()'s read of _fwdm.popitem() then
+escaped the count, so only one of a removal's two writes could be refused and
+test_remove_fails_clean_when_a_backing_mapping_refuses[popitem-bidict] failed.
+
+This patch has the fixture take MutableMapping's popitem(), which removes via
+__delitem__ on every supported Python, so the count spans both backing
+mappings again. bidict itself needed no change: only the fixture assumed how
+UserDict removes.
+
+Closes: #407
