I've merged the InnoDB and link cache changes so far into CVS; the CVS version, which also includes Erik's anon-user talk code, is running on test.wikipedia.org. I've also put on taw's new math code there, but it's not in CVS yet.
I'm still making tweaks to the InnoDB configuration, and some (oversimple) transaction stuff to cut down on writes from automatic commits.
Now, with any luck I can get that Czech translation fixed up and online tonight...
