SMP support maturity? AMD64x2 or FX-57?

This system (this one, right here, that I'm typing on) is dual
processor, and I installed it fresh with 4-CURRENT just after RELENG_3
was branched.  Except for an excursion on RELENG_5, it's always run
-CURRENT.  Sometimes I'd go a year without updating, sometimes a week.
It's running -CURRENT from a couple weeks ago now.  Sometimes it's a
bit twitchy, but I think running X has a whole lot to do with that,
since MP systems under heavier loads without X would do just peachy
with the exact same build that was flaky here.
