On some BSD somewhere, I was once told to use floating point emulation in
the kernel so that the kernel wouldn't have to save and restore floating
point registers as often when processing system calls.
The MATH_EMULATE stuff in options(4) seems to imply that this option is
useless unless your hardware lacks hardware floating point entirely.
So, did this change? Was it some other system? Am I just confused?
