After over 3 decades of experience with 'exportfs' being totally safe to
run in real time with both userspace and kernel NFSD implementations, it came
as quite a surprise when we did 'mmnfs eport change --nfsadd='...
and it bounced the NFS server on all 4 protocol nodes. At the same time.
Fortunately for us, the set of client nodes only changes once every 2-3 months.
