Comment:

 With the changes I've made in my missingdata branch, I now get the
 following performance numbers:

 {{{
 2.0.0.dev-8a5e2a1
 0.0208129882812
 0.0260510444641
 }}}

 This is because I've changed diagonal to always return a view. Once the
 branch is merged, we can probably close this ticket.
