Unmounting NFS idle clients from server

@Don Cragun,
Yes, I am very much sure most of the client mounts are unused. The performance of the NFS server is stable though, i.e. no immediate load because of the number of clients.
But I wanted to know if there is a way I could unmount the idle clients.
I had written a shell script using output of 'showmount -a' where I can : get all the current NFS clients, the mount points. I can run 'umount <mount_point>' using a for loop but it seemed so extravagant.
I would be happy to share all the script details and the errors it throws to you could help me out.
Thank you

The default value for host is the value returned by hostname(1). The showmount command does not display the names of NFS Version 4 clients. OPTIONS
-a Print all remote mounts in the format: hostname : directory where hostname is the name of the client, and directory is the root of the file system that has been mounted. -d List directories that have been remotely mounted by clients. -e Print the list of shared file systems. FILES
