+Subject: [PATCH] Fix running tests on Python 3.14
+
+In Python 3.14 multiprocessing module changed start method from fork to forkserver. Now child processes don't have access to parent's memory objects, and pathological_tests.py fails. This change move required objects (mostly object initialization) into child's area.
