The issue bpo-26530 added a private C API to manually track/untrack memory blocks in tracemalloc. I was just validated by Julian Taylor who confirms that the API works as expected:
http://bugs.python.org/issue26530#msg291551
So I propose to make the 3 newly added functions public and document them:

I am not sure if _PyTraceMalloc_GetTraceback really needs to be a public function.
Exposing the tracing information should probably just go over python interfaces.

What's the status in numpy? Is the current numpy release able to use CPython 3.6 tracemalloc private functions?

With this changeset it would:

I merged my PR: the future Python 3.7 will provide a public C API to track memory allocations.
