TaskProvider::SuspendRefresh Method ()

It is possible for suspensions and resumptions to be nested. By default every change to the task collection results in a call to Refresh, and the task list updates synchronously when it is called. Suspending the refreshing of the task list allows updates to be batched, which results in a cleaner UI experience. For example, refreshing a long task list on every change will cause the task list scrollbar to shrink and grow in a very visible way. Batching the changes decreases the visual noise.
