License: MIT License
Used in: src/core/utility/linear_pool.h
The LinearPool implementation (and the accompanying Neighbor / Bitset helpers)
in src/core/utility/linear_pool.h is adapted from pyglass, with modifications
(a BlockHeap-compatible reset()/push_block() interface and the use of
MemoryHelper for huge-page-backed allocation). The related BlockHeap design in
src/core/utility/block_heap.{h,cc} is also derived from pyglass.
