unionfs related patch

[Marc G. Fournier]

G'day ...

  David Schultz, in his spare time, has been working through some of the
issues I've been able to 'tweak' in the unionfs code ... as he is
currently working on forward-patching it to -CURRENT right now, he can't
commit the code to the -STABLE tree ... in order to allow others using
unionfs to test the patch (I've been running it a few weeks now on a very
heavily loaded system), with his permission, I've posted the patch for
download at:
