Create a thread‐aware lock‐free queue having the specified `capacity`. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The behavior is undefined unless `0 < capacity` and `capacity <= bdlcc::FixedQueueIndexManager::k_MAX_CAPACITY`.
