-/**
- * The `dart:isolate` library defines APIs to spawn and communicate with
- * isolates.
- *
- * All code in dart runs in the context of an isolate. Each isolate has its own
- * heap, which means that all values in memory, including globals, are available
- * only to that isolate. The only mechanism available to communicate between
- * isolates is to pass messages. Messages are sent through ports. This library
- * defines [ReceivePort] to represent the receiver's end of a communication
- * channel, and [SendPort] to represent the sender's end.
- *
- * All isolates start with an initial receive port, which is set in the
- * top-level property [port]. This port is used to establish the first
- * communication between isolates.
- *
- * Two APIs are available to spawn a new isolate: [spawnFunction] and
- * [spawnUri]. [spawnFunction] creates a new isolate that is using the same
- * source code as the current isolate, [spawnUri] allows spawning an isolate
- * that was written independently.
- *
- * There is currently no way to indicate in the API whether the isolates should
- * run on the same or different threads. The underlying system will schedule the
- * isolate were appropriate. In the near future we will add an API to create DOM
- * isolates. These are isolates that share access to the DOM. All DOM isolates
- * will run on the UI thread.
- *
- * This library is still evolving. New APIs are being added, and some will be
- * deprecated and removed. In particular, the class [Isolate] will be
- * deprecated as soon the dartvm has an implementation working for
- * [spawnFunction] and [spawnUri], and we have an API to spawn DOM isolates.
