Right now it doesn't.  And based on some previous threads, there is a
lot of redesign to do before it can.  But stability needs to come
before scalability.  There's no point in FreeBSD pretending it can
support some arbitrary number of CPUs when it panics due to races
in one of the CPU subsystems - which is my understanding of the
current sun4v state.
