> PR 3844 restores the behavior of 2.7 and 3.3. I propose to merge it first, and develop other enhancements later.

Please don't. This PR reintroduced a bug that I fixed in bpo-18408:

commit c4266360fc70745d49b09f2c29cda91c1a007525
Author: Victor Stinner <victor.stinner@gmail.com>

    Issue #18408: Fix _PyMem_DebugRealloc()
    
    Don't mark old extra memory dead before calling realloc(). realloc() can fail
    and realloc() must not touch the original buffer on failure.
    
    So mark old extra memory dead only on success if the new buffer did not move
    (has the same address).
