I'm going to mark this as "returned with feedback". For the next 
version, I'd like to see the API changed per above. Also, I'd like us to 
do something about the tidbitmap overhead, as a separate patch before 
this, so that we can assess the actual benefit of this patch. And a new 
test case that demonstrates the I/O benefits.
