Has anyone evaluated the new "fixed" locking in NFSv4 for use with

which he spent a good deal of time on NFSv4 (supposedly) fixes the
locking shortcomings and can be used as a native file system.

I doubt it, very much.
While your pessimism about NFS is very very justified it would still be
nice if there existed some way of testing locking and other aspects
important for a mail server. NFSv4 is a very different beast from NFS,
redesigned from ground up. E.g. locking is not a clumsily constructed
add on but was planned for from the start. It also has read and write
delegation which should take care of some of your other complaints about
NFS. For example, if you are granted read delegation no other client
can write to the file. With write delegation no other client can write
to or read the file.
Just saying it might warrant another look - if nothing else to discover
from what shortcomings it suffers...
