esid: sec-atomics.isLockFree
description: >
Atomics.isLockFree returns a boolean that indicates whether
operations on datum of size will be performed without the agent
acquiring a lock outside of size bytes.
info: |
Atomics.isLockFree( size )
1. Let n be ? ToInteger(size).
2. Let AR be the Agent Record of the surrounding agent.
3. If n equals 1, return AR.[[IsLockFree1]].
4. If n equals 2, return AR.[[IsLockFree2]].
5. If n equals 4, return true.
6. If n equals 8, return AR.[[IsLockFree8]].
7. Return false.
