Here's my crazy idea that's been knocking around my head for a while. I wonder if anyone can shoot in down in flames.
Remove the ob_type field from all PyObjects. Make pymalloc mandatory, make it use type specific pools and store a pointer to the type object at the start of each pool.
How would you get from the pointer to the pool head?
Did you read the rest of my mail? Maybe I was too terse, but my thinking was that the pools are aligned on a known size boundary (e.g. 4K) so to get to the head you just mask off the 12 (or whatever) least significant bits. Wouldn't work for zeta-c[1], I'd have to admit, but do we care? Cheers, mwh [1] http://www.cliki.net/Zeta-C -- SPIDER: 'Scuse me. [scuttles off] ZAPHOD: One huge spider.
