IMHO UBC shouldn't be used at all by default until such big problems will
be fixed.

yes it makes things faster while running few processes, but under real
heavy load it makes huge problems.

even my father (knowing nothing about NetBSD except that it exist and
nothing about my upgrade) asked "what you changed, now it takes muuuch
longer to fetch my mails, not just today, but since last week".
