The GenericEditor's view-model context is not disposed until the workbench is shut down.

The problem is that the TreeMasterDetailComposite created by the editor moves controls into a "limbo" shell off-screen, which is never disposed until the Display is disposed at shutdown of the platform.  Only then is the disposal hook that was added to the "limbo" shell by the AbstractSWTRenderer::finalizeRendering(Composite) method invoked to dispose the renderer and, therewith, the view-model context (by virtue of its last "user" being removed from it).
