No no no no no, and 5*-1 beats a +1 even from the BDFL <wink>.
Vanilla pymalloc is perfect for this: many small objects. A custom free
list for cells is a waste of code, because a cell never goes away until the
module does: cells will not "churn". We'll get a lot of them, but most of
them will stay alive until the program ends, so the tiny performance gain
you may be able to get from a thoroughly specialized free list "in theory"
will never be realized in practice.
