/**
* Delayed label provider can trigger tree item updates called in the
* viewer after the tree item itself got disposed. This happens especially
* if items appear and disappear very fast within the tree which then will
* lead to nasty SWT Widget already disposed exceptions.
* The SafeTreeViewer wraps an SWT TreeViewer in order to avoid
* exceptions due to accessing already disposed items.
*
* The main reason for this wrapping is that delayed label providers
* (i.e. instances of {@link IDelayedLabelDecorator}) can trigger tree
* item updates called in the viewer after the tree item itself got
* disposed already. This happens especially if items appear and
* disappear very fast within the tree which then will lead to nasty
* SWT Widget already disposed exceptions.

* Clients may subclass this class.
