this discusion has centered around removing the locks of an export.
we also want the interface to ge able to remove the locks owned by a single 
client. this is needed to enable client migration between replica's or between 
nodes in a cluster file system. it is not acceptable to place an entire export 
in grace just to move a small number of clients.
