Core.Concurrency (Visera.Core.Concurrency)

Core.Concurrency provides concurrency utilities: async execution and lock-free MPSC (multi-producer/single-consumer) and SPSC channels. For task queues, event dispatch, and lock-free message passing between threads; does not depend on OS thread primitives (threads and locks are in OS.Thread).

Responsibilities

• Async: Async execution and Future-style interface (if provided) for running work in the background and getting results.
• Channel: Lock-free queue abstraction; MPSC allows multiple producers to one consumer; SPSC is single-producer single-consumer with lower latency. For work stealing, event-bus producer side, etc.

Difference from OS.Thread: OS.Thread provides threads, mutexes, condition variables, atomics, and thread-local queues; Concurrency focuses on task/message channels and async patterns. Both can be combined.
