Ah, I'd missed that.  Thanks for pointing it out.

I'm okay with that if we can't find another way.  However, shouldn't
we be able to statically initialize the raw allocator in _PyRuntime,
much as we were doing before in obmalloc.c?  I have a rough PR up:

    https://github.com/python/cpython/pull/4481

Also, I opened https://bugs.python.org/issue32096 for the regression.
Thanks for bringing it up.
