* Provide a LaunchLooper that receives launch messages and executes the launch 

functions provided with the given arguments.
* Make use of that looper to replace spawning a thread for each launch task.

On the one side this reduces the amount of used threads (and should fix #698)
and on the other side it makes the order in which refs are sent a bit more
predictable.
