My initial reaction is that we should prohibit overlapping stencil and value 
ranges, since (1) there's no general-purpose way to detect overlap cheaply and 
(2) handling the overlap case requires additional copies, which will slow down 
the more common usage.

My two cents:   If the documentation simply stated that overlapping stencil and 
value ranges are not supported, I would not have attempted this in the first 
place.  In general I would encourage the library to avoid as much internal 
memory allocation as possible and leave the burden on the user to ensure that 
there is no overlap.
