If you're storing indexes in NFS, it should kind of work with 1.0-tests 
as long as you set mmap_disable = yes and if you don't have lockd set 
lock_method = dotlock.

There are still some bugs with that setup though, especially cache file 
probably complains about corruption once in a while. It should fix 
itself always, but I guess it's possible that it might sometimes return 
invalid replies to client. Or depends on what the bugs are..

Also doing concurrent accesses to same mailbox in multiple sessions 
might sometimes give "stale NFS handle" errors which Dovecot doesn't 
yet handle everywhere.
