each isolate or native port had a dedicated thread. Refactored the MessageHandler api... - Added a Run function to allow a MessageHandler to run on a ThreadPool. These functions take a start and end callback to allow for isolate initialization and shutdown. - Made the queue private to the MessageHandler and moved all message processing code inside the MessageHandler (got rid of all of the different flavors of RunLoop). This helps remove some code duplication and hides the details of how messages are handled. - Moved all locking and notification out of MessageQueue and moved it up to MessageHandler. Moved OOB support out of MessageQueue and up to MessageHandler. These changes make the MessageQueue much simpler. - Refactored native port and isolate MessageHandlers to share more code. - Improved --trace_isolates output. - Added tests for MessageHandler. Refactored lib/isolate code... - Use the new MessageHandler::Run api. - Got rid of the LongJump stuff in RunIsolate. No longer needed. - Use the new StartIsolateScope/SwitchIsolateScope to make the code less verbose and less error-prone. - Store top-level isolate errors in the sticky_error. Added StartIsolateScope/SwitchIsolateScope classes.
