Comment (by SimonKing):
After looking at #13605, I am not sure if it will be fixed any time soon,
partially because it depends on another ticket that currently needs work.
Hence, as a short term solution, one could consider to finalise the
experimental patch from here and make #13605 depend on it.
Anyway, with the experimental patch, the speed regression (or at least the
abundance of needless function calls for computing X*X) vanishes, and the
only doctest failures are in partitions.py, which can probably easily be
fixed.
