#1874: savemat test failure for OrderedDict on py33
 Reporter:  rgommers  |       Owner:  mbrett
     Type:  defect    |      Status:  new   
 Priority:  normal    |   Milestone:  0.13.0
Component:  scipy.io  |     Version:  0.11.0
 Keywords:            |  
 Happens about half the time, code doesn't seem to care about ordering.
 Also an issue for 0.12.x, but not critical imho - will mark as knownfail
 on >= 3.3 there if this isn't fixed on time.

 Introduced in commit c91d47da9e9.
