> 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.
