Be sure to set the sync option in your exportfs lines.

There is a long history here; see nfs.sourceforge.net and the howto 
(http://nfs.sourceforge.net/nfs-howto/ar01s05.html#sync_versus_async) 
specifically.

Basically, if async is used by the server, the server has permission to ignore 
client O_SYNC requests.
