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.
