Currently I am leaning towards 2) or 3).  What is your opinion?
(1) and (2) are how other archs like Alpha and Itanium deal with
this. I think (3) is likely to be painful to debug 
The good news is that I have already got it implemented and it
survived fairly stressful FPU tests.  :-)

Yes, 3) is a little harder to maitain.  I don't have much clue

Presumably if there is only one FPU intensive process in the
system, it can improve a little bit.

Thanks for the feedback.
