so the following *should* do the trick (assuming mktemp exists, of 
course).  I'm only concerned with removing "inheritance" from a single 
parent directory.

#!/bin/sh
foo=`mktemp -d /tmp/ggXXXXXX`
if [ -d ${foo} ] ; then
   if [ -d $1 ] ; then
     chmod --reference=$1 ${foo} # save old value
     chmod 0777 $1               # hopefully this is different
     chmod --reference=${foo} $1 # restore old value
   fi
   rmdir ${foo}
fi
