On that note;
currently the MySQL server is running at 99.5% CPU.
Whatever it's doing, it's slowing the wiki to a trickle; I can't even
get a connection through.
...and we're back online, after an outage of about 2 and a half hours.
I just noticed the outage, so I killed and restarted MySQL. I guess
I picked a bad time to tell people to start ad-hoc queries.
