10-50 extra binds won't be noticed at all as far as
performance goes.  Unfortunately for you, they also
won't be noticed at all as far as rio goes.

If you create a rio window and then you change
the name space sitting under rio, the existing window's
name space (which has already been copied from rio)
doesn't inherit the new path.  So just re-binding things
doesn't work as you might hope.

This sort of thing comes up enough that I think it
would be nice if it did work (some new flag to rfork),
but it's not there now.

One quick and dirty option is to have cifs echo the
necessary bind commands to standard output (hopefully
cifs dissociates from the name space in which it is mounted)
and run something like:

  cifs | rc; srvfs dfs /n/cifs
  mount /srv/dfs /n/dfs

Then you will see the changes under /n/dfs because of the
extra exportfs (inside srvfs) mount combination.
