0:00 The last data structure or idea that we gotta cover when we think about how Python
0:05 is working with small objects are arenas. And arenas are 256 kilobytes of memory, they're allocated on the heap and they manage 64 pools.
0:16 You can see down here the data structure that defines them. It's quite similar to the pools. You've got doubly linked list.
0:22 You've got the next free one. Things like that. These arenas, this is the top level thing. Arenas contain a bunch of pools.
0:29 Arenas are always the same size. The pools are often the same size, the blocks that they contain, they might be different scale,
0:38 they might be 8 byte objects, they might be 16 byte objects, though, you know, the second would only hold half as many as before,
0:45 but that's the idea. We've got arenas that control the pools, the pools hold the blocks, and the blocks are where the objects actually go
0:53 with 8 byte alignment.
