When the DirectShow graph is done being built, there's no need to wake up any blocking calls on the main thread since setting a source is done asynchronously anyway. This could cause synchronous operations (like stopping or changing the video output) to end prematurely if called while a source was still being loaded, in turn causing the deadlock.
