https://github.com/saroka/resque-lock-timeout

A Resque plugin. Adds locking, with optional timeout/deadlock handling to resque jobs. Using a `lock_timeout` allows you to re-aquire the lock should your worker fail, crash, or is otherwise unable to relase the lock. i.e. Your server unexpectedly looses power. Very handy for jobs that are recurring or may be retried.
