It would be possible to store both the arena index and the arena base address in each pool header. Then we could check that

poolheader* p = pooladdress(somememoryaddress); if (p->arenaindex < narenas &&_ _arenas[p->arenaindex] == p->arenabase) { it's a pymalloc address } else { it isn't } I like that.

No I don't: I hate that. It can be tricked.
