Overview
A fiber-safe mutex.
Provides deadlock protection by default. Attempting to re-lock the mutex from the same fiber will raise an exception. Trying to unlock an unlocked mutex, or a mutex locked by another fiber will raise an exception.
The reentrant protection maintains a lock count. Attempting to re-lock the mutex from the same fiber will increment the lock count. Attempting to unlock the counter from the same fiber will decrement the lock count, eventually releasing the lock when the lock count returns to 0. Attempting to unlock an unlocked mutex, or a mutex locked by another fiber will raise an exception.
You also disable all protections with unchecked. Attempting to re-lock the
mutex from the same fiber will deadlock. Any fiber can unlock the mutex, even
if it wasn't previously locked.
