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.
