That being the case, how about cursor.nextset() returns self.  Two
benefits:

- Allows cursor.nextset().fetchall(), which is nice for interactive
  typing.

- Works nicely if the database-API evolves to treat result sets as
  objects.

Next question: should a programmer be able to do

 	cursor.execute(big_query)
	while cursor.nextset():
		cursor.fetchall()

to process all the rows of all the results, or must the programmer do

 	cursor.execute(big_query)
	cursor.fetchall()
	while cursor.nextset():
		cursor.fetchall()

I personally prefer the former, since cursor.fetchall will usually be
some larger block of code and need to be duplicated.  Other opinions?
