Looks nice! Though I have to say, you should probably avoid sbreak even for small allocations -- obviously it's slow, but even beyond that you have to deal with the fact that it's essentially a global singleton and introduces a lot of subtle failure cases you might not think of + which you can't really solve anyways. It's better to mmap out some chunk of memory and sub-allocate it out yourself.

I hate that very often my first reaction to Show HN posts like this is to cynically look for signs of blatant AI code use.
I don't think that's the case here though.
