Description

This is something of a mega tracking issue.  Once the dataset is reading asynchronously we can start converting the readers to be asynchronous.  The primary goal is to keep blocking reads off the CPU thread pool.  So "asynchronous" in this case means using the IOContext instead of the CPU thread pool.
