> Reporter: Pavel Tupitsyn

> Fix For: 1.5

>
> Currently we use TaskFactory.FromAsync to create tasks and return them from
> API. This requires implementing IAsyncResult, which has a heavyweight
> WaitHandle inside. TaskFactory then uses
> ThreadPool.RegisterWaitForSingleObject to wait on that handle and set task
> completion.
> Creating WaitHandle and waiting on it are redundant extra steps.
> System.Threading.Task has internal API to create "promise-style" task and
> then set it to completed state when needed.
