This means that the combined loadable will be pending while any of the branches

// https://github.com/elm/core/issues/980

// Why use true/false here? Why not just check the length of the queue?
// The goal is to detect "are we currently dispatching effects?" If we
// are, we need to bail and let the ongoing while loop handle things.
//
// Now say the queue has 1 element. When we dequeue the final element,
// the queue will be empty, but we are still actively dispatching effects.
