The exit() routine (in kern_exit.c) has a line I don't understand.
Right after a process releases the memory for its page tables and u area,
there is an spl5() call like so:

	vrelpt(u.u_procp);
	vrelu(u.u_procp, 0);
	(void) spl5();		/* hack for mem alloc race XXX */

Does anybody know what race they're talking about?

Please respond directly to me.  Thanks a great deal for any help you
can offer me.
