In Ifpack2::RILUK::initialize(), there is a sometimes-unnecessary memory transient.
Created by: ambrad
#570 (closed) focused on making RILUK reusuable. As a side effect, it confined a memory transient (a CRS copy of the matrix) to initialize(); previously, it persisted over the lifetime of the RILUK object.
The objective of this issue is to remove the transient completely in most use cases.
