All of the updatemanager stuff is tied to the canvas so when the
document isn't associated with the canvas any more that all shuts down
and disconnects from the document.

Right we don't wait for the updatemanager queue to finish before
shutting it down (as it might well never be empty).

This is the solution I would recommend. This will also have
better performance when switching back since the canvas won't
have to rebuild the entire graphics tree.
