Is it safe to mount a nfs file system at two mount points simultaneously,
i.e. using a fstab with lines

   host:/export /mnt1 nfs rw 0 0
   host:/export /mnt2 nfs rw 0 0

(yeah, it's probably better to use symlinks, but this would simplify
things for me. But I won't do it if I'll lose due to cache inconsistencies
or whatever...)
