# inspired by http://ariejan.net/2010/08/23/resque-how-to-requeue-failed-jobs

# retry all failed Resque jobs except the ones that have already been retried
# This is, for instance, useful if you have already retried some jobs via the web interface.
Resque::Failure.count.times do |i|
  Resque::Failure.requeue(i) unless Resque::Failure.all(i, 1)['retried_at'].present?
end

# retry all :)
Resque::Failure.count.times do |i|

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.
