-* Experiment with multi-threaded backend better resource utilization
+* Experiment with multi-threaded backend better I/O utilization
- This would allow a single query to make use of multiple CPU's or
- 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.
