It's just NFS. nfsd does open/getdents/close on every readdir request. "rm -r" is the application that tends to detect any problems with cookie handling between the NFS client and server.
(I'm sure there was once an 'rm -r' that used telldir/seekdir, but I cannot find it. Maybe it was level-7 UNIX :-)
