Yes, I understand the concern, which is not that important if you use a debugger and step into the function to see if it is run immediately. We write functions because they are a way to avoid duplicating code. The block:

if (isMainThread()) {
// do
} else
 RunLoop()...

happens a lot and I think it can be simplified in many places.
