You should really start reading the source code. See Modules/gcmodule.c. To answer your question: neither, nor. All objects are in one region, and there is no pointer separating the generations. Instead, all objects belonging to one generation form a double-linked list. > I propose to track hot spots in python, that is contexts where most of > allocations occur, and instrument these with counters that essentially > tell how often an object generated here ends up killed in ephemeral, > short-, long-lived garbage collector run or is in fac tstill alive.

We would consider such a proposal only if you had *actual evidence* that it improves things, rather than just having a reasoning that it might.
