 * The macro below closes file descriptors inherited from the process

 * after the start of main() in order to get consistent results across
 * different releases. Known behavior:
 * - Fedora Core 1's Perl opens /dev/pts/2 as fd 10.
 * - For Ubuntu 8.04, see also
 *   https://bugs.launchpad.net/ubuntu/+source/seahorse/+bug/235184
