FPU emulator unsafe for SMP?

I have been chasing a FPU register corruption problem on a SMP box.  The
curruption seems to be caused by FPU emulator code.  Is that code SMP safe? 
If not, what are the volunerable spots?

Just thought I'd check before I dive into it ....

BTW, I think even with the latest fpu emu patch, the classic fpu/signal
problem is still there.  I will post in a separate email later.
