I was under the impression that some NFS server implementations don't
have stellar maildir performance with Dovecot clusters due to the NFS
caching problem, and locking, which is why I made the distinction
between something like a NetApp and a DIY NFS server.  Is this not true?
 Or is this NFS version dependent?  Or is my recollection simply faulty?
