LOL, yeah, no.  That's 33+ seconds of wasted time.  From a *KVM* perspective, this
is quite binary: either KVM intercepts HLT or it doesn't.  Any timing bugs would
be purely CPU bugs.

Please adjust this to have the default runtime <1 second.  If you feel strongly
about the need for a long-running test, feel free to add a command line option
to control the number of iterations.
