Summary:
The original design of RCTSurface implied that the Surface starts on initialization and stops on deallocation. Recently I realized that this not sufficient API in some cases when the application uses ARC with autorelease pools (that can postpone object deallocations, which is highly undesirable).
And that's simply handy to have those methods sometimes.
