Modules

concurrent_hash_map

Sharded concurrent hash map with per-segment locking.

futex_mutex

Futex-backed mutex with OS-assisted parking for fair, contended sections. Mutex backed by a Linux futex, with a condvar fallback elsewhere.

resource_pool

Sharded pool handing out reusable resources without a global lock.

spin_lock

Spin lock for critical sections short enough that parking costs more than spinning.

wait_group

Barrier that releases once a counted set of tasks has completed.
