# TEST	recd024
# TEST	Test recovery of streaming partial insert operations. These are 
# TEST	operations that do multiple partial puts that append to an existing
# TEST	data item (as long as the data item is on an overflow page).
# TEST	The interesting cases are:
# TEST	 * Simple streaming operations
# TEST	 * Operations that cause the overflow item to flow onto another page.
# TEST
