Function pullPromise

(promise: RpcPromise)

// Given a promise stub (still wrapped in a Proxy), pull the remote promise and deliver the
// payload. This is a helper used to implement the then/catch/finally methods of RpcPromise.
async function pullPromise(promise: RpcPromise): Promise<unknown> {
  let {hook, pathIfPromise} = promise[RAW_STUB];
  if (pathIfPromise!.length > 0) {
    // If this isn't the root promise, we have to clone it and pull the clone. This is a little
    // weird in terms of disposal: There's no way for the app to dispose/cancel the promise while
    // waiting because it never actually got a direct disposable reference. It has to dispose
    // the result.
    hook = hook.get(pathIfPromise!);
