IMHO delegation and/or write locks gives a client adequate control
over consistency if it cares.

I also won't be shocked if some clients that use a compound RPC that
looks like wcc_data make the mistake of assuming that it can be used
the same way as wcc_data, but...

As an aside, I recall that I had a vnode lock on the file that was the
CFH in my server when I first coded it, which would have provided atomicity
(is that a word?). I rapidly discovered that was
a "bad idea" when I started testing. (I don't remember the specific cases,
but it didn't take long before it got hung.)

Just my $0.00 worth, rick
