Adding in Isaku's last patch and testing on an HVM domain, it doesn't
take long to hit problems.  4-way/4G HVM guest running 4 instances of
the test program in parallel will eventually get this in the guest
kernel:

handle_fpu_swa: fp_emulate() returned -1

and the test program gets killed with a SIGFPE.
