Agreed. It isn't "incompatible" per se but it is certainly not the
intention anymore. With kernel preemption, we plan to cleanly tackle
the lock hold times.
But maybe that is what the above means ... not "low-latency" per se but
the general reduction in lock hold times and improvement of algorithms.
This is something Andrew, myself, and others are working on. It is the
follow up work to preempt-kernel.
