/* Overview
*
* class RadosIo
* An IoExerciser. A simple RADOS client that generates I/Os
* from IoOps. Uses an ObjectModel to track the data stored
* in the object. Uses DataBuffer to create and validate
* data buffers. When there are not barrier I/Os this may
* issue multiple async I/Os in parallel.
