READDIRPLUS can be a performance hindrance when the client is working with large directories. In addition, some servers still have bugs in their implementations (e.g. Tru64 returns wrong values for the fsid). Add a mount flag to enable users to turn it off at mount time following the implementation in Apple's NFS client.
