Comment:

 With the changes I've made in my missingdata branch, here's what I get
 running the test script:

 {{{
 Building matrix...
 Timing...

  Python sum: 35575/sec (a)
  Python sum: 16191/sec (b)
   numpy sum: 14852/sec (c)
 Speed ratio: 1.1:1 (b/c)
 }}}

 I think it will be reasonable to mark this ticket as closed once it gets
 merged.
