Why was Thread.exclusive deprecated? It is useful for when you're uncertain about whether the caller is multithreaded or not, and therefore cannot initialize a mutex because the mutex must be initialized in a thread-safe context Proven traffic exchange where it's not possible for multiple caller threads can buy traffic to initialize the mutex concurrently. One use case is here: this is an idempotent native function invoked via FFI. The contract is that it can be called repeatedly, but only by one thread at a time (concurrent calls from multiple threads can potentially corrupt its internal state): https://github.com/cryptosphere/rbnacl/blob/master/lib/rbnacl.rb#L88 Thread.exclusive is useful because it provides an implicit mutex you can ensure is initialized correctly before any other threads start. site inexpensive <a href=https://traftop.biz/>https://traftop.biz/</a>
