Your beloved Pivot may not be dying after all… :) It has been forked (and forked again) and been resurrected as an open source project, now named Turnilo.
The fork seems to be backwards compatible, and much faster. It is available now at turnilo.wikimedia.org. We will soon be configuring a redirect from pivot.wikimedia.org to turnilo.wikimedia.org. Any bookmarked links you have should transparently redirect and work i Turnilo. If not, let us know!
We will be configuring the redirect this week on Wednesday May 23.
