          Re Bob Mathiesen's note: I checked umertvit'/umershchvljat'
          in the 17-volume dictionary and Evgen'eva, where it has no
          stylistic mark at all (and lots of clearly non-ChSl examples
          in the 17-volume dictionary), and in Ushakov, where it is
          only marked as "knizhn."  Sounds to me like high-style
          Russian, not Church Slavonic.
