The problem is though that when you chdir() into an automount mount
point, automount aill automatically mount it for you.  Hence if an
automount filesystem wasn't already mounted, if you chdir() into it it
immediately becomes a "just-now-changed" mount point.  That's the
essensce of the problem I am trying to solve.
