Something you should know if you haven't discovered it since your email:
turning thread support on and off is only supported by the command-line flags

If ye love wealth greater than liberty, the tranquility of servitude greater
than the animating contest for freedom, go home and leave us in peace. We seek

and may posterity forget that ye were our countrymen. - Samuel Adams
