Revision 1462060

  Mark the profiling step of new apis as completed. Over the last few months
  I profiled all the cases I profiled before (status, update, merge, copy,
  etc. etc.) and found no new problems.
  
  Of course we can always improve further, but the original db query work I
  did earlier in 1.8 development and the verifications added back then now
  show a lot of improvement over 1.7 and no recent regressions.
  
  I call this done for 1.8. And if we find and solve new problems we can try
  to backport them.
