0.6.12.8:
	merged flaky1 branch back into main branch, now that it's
		stable again.
	(Dan Barlow's email on sbcl-devel warned that one problem
		with branches is that useful checkin comments
		end up being hard to find when they're stuck on
		branches. I'll check the cvs2cl.pl output
		after this checkin, and if it doesn't include
		the notes for the various checkins on
		the flaky1 branch, I'll make another checkin
		below just as an excuse to add log notes which
		copy or summarize them.)
	The flaky1 branch was rather a lot of work for what turned
		out to be not very many fixes. ("The discipline of
		refactoring is hard to learn and easy to
		lose sight of, even if only for a moment. I
		still lose sight more often than I care to admit.
		I'll do two or three refactorings in a row without
		rerunning the test cases. Of course I can get away
		with it. I'm confident. I've practiced. Boom! A
		test fails, and I can't see which of my changes
		caused the problem. At this moment, you will be
		mightily tempted to just debug your way out of
		trouble. After all, you got those tests to run
		in the first place. How hard could it be to get
		them running again? Stop. You are out of control,
		and you have no idea what it will take to get back
		in control by going forward. Go back to your
		last known good configuration after each one."
