There is a simple fix to sohasoutofband() in sys/socket.c that will
prevent one kind of dtom panic:

	sohasoutofband(so)
		struct socket *so;
	{
		mapinfo map;

wrong!		savemap(map);
		if (so->so_pgrp == 0)
			return;
right!		savemap(map);

Remove the savemap(map) call before the if/return and place it after them.
That removes the possibility of an unbalanced savemap/restoremap pair.
