object->unlink is often defined on objects that need to inform some other object that they are destroyed. For example, graphical objects inform their device to allow the device to remove the object from the display and update their book-keeping.

The method object->unlinking is provided as a test whether or not object->free is in progress on the receiver.

See also visual->destroy to destroy entire hierarchies of (visual) objects.

Diagnostics: Fails silently if object<->protect equals @on.

Bugs: Window object->free should just delete the window from it's object<-frame. In new code, please delete frames using object->free.
