cc: Reorder TileManager shutdown and add debugging information.

This patch changes the order of shutdown from clearing orphans then
completing tasks to first complete the tasks then clean orphans, since
task completion causes more orphans to be generated.

Also, this adds debugging information to ImageManager to narrow down
the time when crash in the referenced bug happens.
