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

commit d63a3b8beb4a0841cb59fb3515347ccaab34b733
Author: Martin v. Löwis <martin@v.loewis.de>

    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.
