sidekiq-worker-killer

Sidekiq is probably the best background processing framework today. At the same time, memory leaks are very hard to tackle in Ruby and we often find ourselves with growing memory consumption. Instead of spending herculean effort fixing leaks, why not kill your processes when they got to be too large?

Highly inspired by Gitlab Sidekiq MemoryKiller and Noxa Sidekiq killer.
