The Deadlock Clock is a three-day timer used on stale threads. The idea is to get the thread moving in that time — promoting discussion, hooking a crowner, or similar — and if nothing happens then it's locked and moved to one of the morgues for old threads. This means that TRS and IP aren't quite so full of discussions nobody is replying to.
