Thread:Support/HHVM

As some of you might have noticed, HHVM is now available via beta features.

Known issues:
 * It sometimes crashes or gets stuck. If that happens, you can remove the hhvm=1 cookie, disable new cookies (because otherwise it gets added back) and go to preferences to disable it.
 * Category listings may not work. Possible fix has been made upstream.
 * Our workaround for supporting different scripts in graphs made by Special:TranslationStats is not working for unknown reason.
