    When CEF3 sub processes generate events they use SendMessage to post the event to the ActiveX process.

    However, SendMessage is blocking and the event fired must return before any other WebKitX API can be called.

    This setting enables a mechanism where event data are copied to a queue and a timer fires the events by reading the queue.

    In essence this makes the event fire in its own stack instead of the SendMessage IPC stack.

    You should use this for Single Threaded clients as it improves performance and compatibility.
