Server will probably be slow overnight and possibly most of the day tomorrow. Someone over at Gentoo got bored today and updated just about every package they have and the server will be doing lots of re-compiling for a while.
Update: Doh! I just figured out what I did. I caused this myself. While trying to get Mailman working earlier, I un-masked all the un-stable, but not yet approved stuff. Just re-masked everything and now I have nothing to update. Whew! No more slow server.
