RawReceivePort class

A low-level asynchronous message receiver.

A RawReceivePort is low level feature, and is not Zone aware. The handler will always be invoked in the Zone.root zone.

The port cannot be paused. The data-handler must be set before the first messsage is received, otherwise the message is lost.

Messages can be sent to this port using sendPort.
