nit: Could be a private inner class (or could be in a separate file)

[horo, 2014/05/08 14:17:46]

Done.

Does this need to be ref-counted?

[horo, 2014/05/08 14:17:46]

EmbeddedWorkerInstance could be deleted while the thread hopping.
 IO-thread DevToolsManagerBridge::RegisterToDevToolsManager()
 UI-thread RegisterToDevToolsManagerOnUI()
 IO-thread DevToolsManagerBridge::RegisteredCallback()
So I think it must be ref-counted.

[kinuko, 2014/05/08 16:34:57]

This doesn't necessarily mean we need ref-counting.  Also now that most of
devtools related code is in this file having this class may not be that
important.
