unfortunately this only works for MMX not for real fpu (due to exception
handling uglies)
Perhaps there should be a comment to that effect? Neither the code nor
Documentation/preemt-locking (which mentions the fpu) says anything
about this little fact.
It's also broken for x86-64, which uses sse for floating point, not the
x87 fpu.
