> 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.
> [TaskCompletionSource|https://msdn.microsoft.com/en-us/library/dd449174(v=vs.100).aspx]
allows lighter-weight approach.
