   * 4 -> 5 at the same time. GIO previously attempted to handle this by naively
   * dup'ing the source fds, but this was not good enough because it was
   * possible that the dup'ed result could still conflict with one of the target
   * fds. For example:
   *
   * source_fd 5 -> target_fd 9, source_fd 3 -> target_fd 7
   *
   * dup(5) -> dup returns 8
   * dup(3) -> dup returns 9
   *
   * After dup'ing, we wind up with: 8 -> 9, 9 -> 7. That means that after we
   * dup2(8, 9), we have clobbered fd 9 before we dup2(9, 7). The end result is
   * we have remapped 5 -> 9 as expected, but then remapped 5 -> 7 instead of
   * 3 -> 7 as the application intended.
   *
   * This issue has been fixed in the simplest way possible, by passing a
   * minimum fd value when using F_DUPFD_CLOEXEC that is higher than any of the
   * target fds, to guarantee all source fds are different than all target fds,
   * eliminating any possibility of conflation.
   *
   * Anyway, that is why we have the unused_pipefds here. We need to open fds in
   * a certain order in order to trick older GSubprocess into conflating the
   * fds. The primary goal of this test is to ensure this particular conflation
   * issue is not reintroduced. See glib#2503.
   *
   * This test also has an alternate mode of operation where it instead tests
   * for conflation with gspawn's child_err_report_fd, glib#2506.
   *
   * Be aware this test is necessarily extremely fragile. To reproduce these
   * bugs, it relies on internals of gspawn and gmain that will likely change
   * in the future, eventually causing this test to no longer test the bugs
   * it was originally designed to test. That is OK! If the test fails, at
   * least you know *something* is wrong.
