TabbedLanguages rewrite

I seem to be getting a lot of script timeouts now. Could this be related?

I thought for a while that it is either this or my OrangeLinks rewrite, but now I suspect that this is MediaWiki acting up. We have had an update recently, and I vaguely remember similar problems on previous update… they might have downgraded libraries to alleviate that. Or something like that. I cannot really recall the details.
