You probably want to delay the re-evaluation (with something like
asyncExec) instead of doing it when a notification arrives, to avoid the
"event storm" problem. For long lists, you can re-evaluate only visible
items to make this scale. ComputedValue together with things like
ControlUpdater, TableUpdater, etc. already implement some of this.
