SysNotifyBroadcast will be synchronous, even if you have multiple tasks.
The background task will block until the UI task finishes handling the
notification.
If you use SysNotifyBroadcastDeferred, this won't be the case, but then
you'll be essentially using the event loop in the UI thread to do your
message passing.
In short, the notify manager is not the right tool for inter-task
communication.
...but the point is moot, since as Jim pointed out we don't support normal
apps spawning a background task.
