-// Uni-directional MessageProcessor "pipe" that accepts messages on
-// one thread and dispatches them to a MessageProcessor on a different
-// thread.
-//
-// Typical usage involves:
-// 1. Create the pipe on the "main" thread, specifying the target thread's
-//    task runner.
-// 2. Take one or more MessageProcessor proxies from it.
-// 3. Post a task to the target thread to set the target MessageProcessor.
-// 4. Start using the MessageProcessor proxy(/ies) on the main thread.
-// 5. When the target MessageProcessor is about to be destroyed on the
-//    target thread, destroy the pipe instance immediately beforehand.
-//    Any messages that are subsequently passed to a proxy, or are already
-//    in-flight to the pipe, will be silently dropped.
