it would allow a piece of code to affect the behavior of completely
unrelated pieces of code by screwing with global rounding mode bits.
That's not going to happen.
I believe there have been proposals to allow greater access to IEEE
floating point intrinsics, and I suspect they were better engineered for
modularity. Perhaps one of the other readers of this list remembers enough
details to give you a good citation.
