I assumed it wouldn't use two processors on one query. I was wondering if
independent queries would automatically use multiple processors when
available; or if some special action had to be invoked (like compile time
switch or config option) before this behaviour was possible. Sounds like
we get this behaviour "out of the box". Great.
