Misc #11904: Why was Thread.exclusive deprecated?
https://bugs.ruby-lang.org/issues/11904#change-90336

* Author: bascule (Tony Arcieri)
* Status: Rejected
* Priority: Normal
----------------------------------------
initialize a mutex because the mutex must be initialized in a thread-safe context where it's not possible for multiple caller threads 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.
