So my check below doesn't work. Add here:

if (errno != EINVAL)
  i_error("errno = %d %m");
else if (fstat(l->fd, &st) < 0)
  i_error("fstat() failed: %m");
else
  i_error("mode=%o & fifo = %d", st.st_mode, S_ISFIFO(st.st_mode));
fd_debug_verify_leaks(l->fd, l->fd); // should show what it is if it's not a fifo..
