Mostly so I can see if we can close any bug reports.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">A TaskManager.Backend objects is owned by the taskItem - so the lifespan of the TaskItem will <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">always</em> outlive the Backend - so we shouldn't need a smart pointer.
The ToolTip is more questionable, it has the same lifespan as the backend, so it's a bit confusing as to which order they get deleted - so there is scope for a problem.</p>
