I would have thought so too, but Strobe seems to indicate otherwise. Or maybe the pipeline just gets bollixed up due to other code around it and there isn't anything I can do to change it. <*Sigh*> It was so much easier when instruction timings were fixed and pipelines carried only oil and natural gas.
