My Ultra2 now has no [GIANT-LOCKED] messages at all during boot and
seems to run without any problems.  I haven't done any performance
measurements yet, and enabling mpsafevfs will probably negate most
improvements that this might have given, but it's a start.

David O'brien:  THIS IS NOT A FREEBSD 5.4 CANDIDATE.  It's a shame that
I'll need to postfix all of my commits from now on with this message.
