The Niagara CPUs are heavily multi-threaded and will require a lot of
parallelism to be exposed to them in order to be effective.

Until Sun makes niagara-based machines with lots of I/O channels, there
won't be much I/O parallelism available to match the CPU parallelism.

Bizgres MPP will use the process and I/O parallelism of these big SMP
machines and the version based on Postgres 8.1 will be out in February.
