Or to use a port on which this dance is unnecessary (VAX comes to mind;
the VAX FPU is tightly integrated with the main CPU and doesn't have
anything like FPU-disabled exceptions or context to save/restore).

Or tweak the port you're using to save/restore FPU state when your code
wants to use it.  (Though I suspect using the word "tweak" may
underestimate the work involved in this option.)
