True that PQ will run on a single-proc. machine, but what good is it? You
just add a bunch more overhead for the PQ enqueue/dequeue and using Oracle
as a process scheduler instead of the O/S, which is more likely to be
optimized for the chip. You can use 100% of the processor with one Oracle
server process, or 100% of the processor with ten server processes. You
just add overhead.
