The fine-grain locking and preemption in 6- and -current
*should* be most of what is required to move towards realtime.
Perhaps throw in a different scheduler for good measure.
Having said that, I don't think that anyone is busy doing any
characterisation of worst-case path lengths and lock-holds,
which is the other side of the equation.
