    The PyUnicode_ClearFreeList() function does nothing since Python 3.3, since this change:

    commit d63a3b8
    Author: Martin v. Löwis <martin@v.loewis.de>
    Date: Wed Sep 28 07:41:54 2011 +0200

    Implement PEP-393.

    I propose attached PR to remove the function.

    It seems like the function is part of the limited API and exported by PC/python3.def. But I don't see any usecase to explicitly clear the unicode freelist. Call gc.collect() to clear all free lists: no private API is needed.
