Description
given CASSANDRA-1155, we should query multiple nodes for the rows corresponding to the given index criteria, such that we have a 90% chance of getting enough rows w/o having to do another query (but, if our estimate is incorrect, we do need to loop and do a 2nd query).
we start with the first node in token order, so that we only have to query a single node for low cardinality (i.e., every index value has many rows associated with it). we do this by ordering the keys in the index row, in partitioner order.
