Detailed Description

Lock-free, obstruction-free, non-coalescing, alloc-only bucket allocator

Loft is a simple lock-free bucket allocator that maintains free-lists without coalescing blocks or releasing memory back to the underlying bump allocator. The free-list buckets are 64 bytes apart and all allocations are 64 byte aligned to avoid false sharing of cache lines. Allocation requests are satisfied with O(1) complexity using lock-free code paths. Because memory is not released back, no block coalescing (or splitting) is implemented.
