We're afraid to try it, honestly.  There's no promise, not even an
indication, that anything has been fixed, and we can't afford to have the
system shutting down like that again.  I would guess that's the situation
with these other guys - we're afraid to "upgrade" because of so many
problems we've had with it before.  Right now, the system is at least
functional.  I am following this bug report, and if we do an upgrade, I'll
post results.
