You can't do this. /tmp on the client is on a different superblock than the nfs mount, and the point of
sillyrename is that it is a rename and not a move. (i.e same inode)
The /tmp on the server is not even accessible on the client, which does the sillyrename.
You'll have to better your scripts to loop and delete until all .nfsXXXX go away because
these are temporarily there until the application on the client stops using the file.
