We generally want to be sure that each test is independent from the
others so creating a separate device for each test function is a good
idea regardless.

Your point about ValidateDevice() is very interesting though, actually
it makes a lot of sense and it probably means that ValidateTechnique()
should delegate a good chunk of its work to ValidateDevice() (not
surprising but somehow I forgot about it). It would be interesting to
extend the d3d9 ValidateDevice() tests at some point.
