      * The technique embodied here works if libc follows the Single Unix Spec
      * and actually uses the storage passed to putenv() to hold the environ
      * entry.  When we clobber the entry in the second step we are ensuring
      * that we zap the actual environ member.  However, there are some libc
      * implementations (notably recent BSDs) that do not obey SUS but copy the
      * presented string.  This method fails on such platforms.  Hopefully all
      * such platforms have unsetenv() and thus won't be using this hack. See:
      * http://www.greenend.org.uk/rjk/2008/putenv.html
      *
      * Note that repeatedly setting and unsetting a var using this code will
      * leak memory.
