    Given the estimated frequencies of a join key in two pipes that we want to skew-join together, this returns the key's replication amount in each pipe.

    Given the estimated frequencies of a join key in two pipes that we want to skew-join together, this returns the key's replication amount in each pipe.

    Note: if we switch to a Count-Min sketch, we'll need to change the meaning of these counts from "sampled counts" to "estimates of full counts", and also change how we deal with counts of zero.
