The following patch allows dumping of live Ruby backtraces of running workers by sending a TRAP signal (kill -5) to the worker PID.
The master also automatically generates a backtrace when it kills a worker due to timeout: this helps identifying what was doing the worker and hopefully give a hint of what was taking so much time.
