If we have just a few allocations, we should use the mmap based allocator. This preserves the invariant that bmalloc can be used as a general-purpose malloc implementation. If we have lots of small allocations, we should probably reconsider the design. I’m not familiar with the new uses of std::vector inside bmalloc. That’s not something I would recommend. Geoff

Hi, WebKittens,
IIRC, bmalloc uses mmap based page allocator for internal memory use. For example, bmalloc::Vector uses it instead of calling malloc. But recent changes start using std::vector, which means it uses std malloc under the hood.
So my question is, if we want some internal memory allocation in bmalloc, shoud we use std::malloc? Or should we use mmap based allocator?
