I have not measured this as I don't have any machines with fpus unfortunately.

Sounds good but I dont know if its possible as data is lost when enterning the 
fline trap maybe there is a way to do it change fpu instuctions to jumps and 
insert the nop there and run the trap.  But I don't know how to go about it as
