 /**
  * 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.

  * [spawnFunction] and [spawnUri], and we have an API to spawn DOM isolates.

I had to create another file because leg does not understand the #native tag. We
don't have any plans on supporting it, but we can workaround it.

-ReceivePort _port;

-SendPort _spawnFunction(void topLevelFunction()) {
-  final name = _IsolateNatives._getJSFunctionName(topLevelFunction);
-  if (name == null) {
-    throw new UnsupportedOperationException(
-        "only top-level functions can be spawned.");
-  }
-  return _IsolateNatives._spawn2(name, null, false);
-}
-
-SendPort _spawnUri(String uri) {
-  return _IsolateNatives._spawn2(null, uri, false);
-}
