Title: Default linuxYield option to false

Roxie's linuxYield option (added a LONG time ago to help reduce latency
on uniprocessor boxes by ensuring that the threads reading data from
slaves were not starved out by tight loops in other queries) has a
major impact on the performance of the memory manager if set.

On today's typical hardware (and typical Roxie usage) it is much more
appropriate to default this option off.
