Fix a regression when a type method like ``__init__()`` is modified in a | |
subinterpreter. Fix a regression in ``_PyUnicode_EqualToASCIIId()`` and type | |
``update_slot()``. Revert the change which made the Unicode dictionary of | |
interned strings compatible with subinterpreters: the internal interned | |
dictionary is shared again by all interpreters. Patch by Victor Stinner. |
