…sses (pythonGH-22020) When allocating MemoryError classes, there is some logic to use pre-allocated instances in a freelist only if the type that is being allocated is not a subclass of MemoryError. Unfortunately in the destructor this logic is not present so the freelist is altered even with subclasses of MemoryError..

When allocating MemoryError classes, there is some logic to use
pre-allocated instances in a freelist only if the type that is being
allocated is not a subclass of MemoryError. Unfortunately in the
destructor this logic is not present so the freelist is altered even
with subclasses of MemoryError..
