We have tst_test.min_cpus, used e.g. in kvm_svm03. But this is a note to 
programmers that they must use pthreads, otherwise tst_kvm_wait_guest() 
will always time out or lock up. The signaling can work even on single 
CPU unless you somehow manage to break task switching in the host kernel 
(like in kvm_svm03).
