Here's the comment from the code (in the CursorResponseMessage class) I 
patched ....

"Due to a change in the fontend-backend protocol version 0 2 0 0, I must 
check to see if another CursorResponseMessage follows right after the 
one that led to my creation.  If there is, I take the last one as being 
the 'correct' one"
   Note: the "I" and "my" in the comment refer to a 
CursorResponseMessage instance.

Also, there was a discussion on this list between Tom and I about the 
change and the direction it implied.  The gist as I recall centered 
around the question of whether every side-effect of a query should 
return a  distinct CursorResponseMessage in addition to the one for the 
explicitly invoked query.
