With the help of QueuedExecution property on the PointBinder, the developer can choose that the operations (such as Write-s) are performed outside the calling thread, and therefore do not block. Typical usage involves a one-time Read or Write linked to a click on a button, which would otherwise block the user interface until completed.

The Boolean QueuedExecution property defaults to 'false'. When set to 'true', the operations on the binder are executed outside the calling thread, but still in the order of arrival. This allows non-blocking operation calls on the binder.
