Heh, this just gets one step closer to a real wmb.  I just used the
correct code from linux, so I think nothing needs to be done in vhost.
Apropos this change in lguest: why is a compiler barrier sufficient? The
comment says devices are run in separate threads (presumably from
guest?), if so don't you need to tell CPU that there's a barrier as
well?

	lguest: clean up length-used value in example launcher

OK, fixing that.

Thanks!
