-//@ Besides `Mutex`, there's also [`RwLock`](https://doc.rust-
-//@ lang.org/stable/std/sync/struct.RwLock.html), which provides two ways of locking: One that
-//@ grants only read-only access, to any number of concurrent readers, and another one for
-//@ exclusive write access. Notice that this is the same pattern we already saw with shared vs.
-//@ mutable references. Hence another way of explaining `RwLock` is to say that it is like
-//@ `RefCell`, but works even for concurrent access. Rather than panicking when the data is already
-//@ borrowed, `RwLock` will of course block the current thread until the lock is available.
-//@ In this view, `Mutex` is a stripped-down version of `RwLock` that does not distinguish readers
-//@ and writers.
