No, we don't buffer cursors. A single cursor bo is updated every time its image
changes. (Whilst possible, I don't it is an interesting optimisation to cache
the bo for a variety of cursors.)

This could just be a bad bit of RAM, bad cache, or signs of incoherency... Can
you retry Daniel's original overkill patch and see if this corruption ever
turns up? Though I think we can safely say that the current mb is an
improvement.
