NFS in 5.x has the same or better consistency guarantees as your
favorite 4.x version.  And in 5.5, you get NFS Version 3 and NFS
over TCP, which work so well and so fast I was amazed when I
started here.  You're clearly out in left field on this topic.

I won't argue about the ills of a larger memory footprint, other
than to comment that 5.5 is much better in that area.
