Description

Utilizing the sequence ids created via the update document
methods, we will enable IndexReader deleted docs over a sequence
id array.

One of the decisions is what primitive type to use. We can start
off with an int[], then possibly move to a short[] (for lower
memory consumption) that wraps around.
