Spit items:
* Experiment with multi-threaded backend better I/O utilization
This would allow a single query to make use of multiple I/O channels
simultaneously. One idea is to create a background reader that can
pre-fetch sequential and index scan pages needed by other backends.
This could be expanded to allow concurrent reads from multiple devices
in a partitioned table.
* Experiment with multi-threaded backend better CPU utilization
This would allow several CPUs to be used for a single query, such as
for sorting or query execution.
