-//! Abstraction over blocking and unblocking the current thread.
-//!
-//! Provides an abstraction over blocking the current thread. This is similar to
-//! the park / unpark constructs provided by `std` but made generic. This allows
-//! embedding custom functionality to perform when the thread is blocked.
-//!
-//! A blocked `Park` instance is unblocked by calling `unpark` on its
-//! `Unpark` handle.
-//!
-//! The `ParkThread` struct implements `Park` using `thread::park` to put the
-//! thread to sleep. The Tokio reactor also implements park, but uses
-//! `mio::Poll` to block the thread instead.
-//!
-//! The `Park` trait is composable. A timer implementation might decorate a
-//! `Park` implementation by checking if any timeouts have elapsed after the
-//! inner `Park` implementation unblocks.
-//!
-//! # Model
-//!
-//! Conceptually, each `Park` instance has an associated token, which is
-//! initially not present:
-//!
-//! * The `park` method blocks the current thread unless or until the token is
-//!   available, at which point it atomically consumes the token.
-//! * The `unpark` method atomically makes the token available if it wasn't
-//!   already.
-//!
-//! Some things to note:
-//!
-//! * If `unpark` is called before `park`, the next call to `park` will
-//!   **not** block the thread.
-//! * **Spurious** wakeups are permitted, i.e., the `park` method may unblock
-//!   even if `unpark` was not called.
-//! * `park_timeout` does the same as `park` but allows specifying a maximum
-//!   time to block the thread for.
