What if there are thousands of jobs in the queue? It doesn't seem right to go reserving a thousand jobs just to put them back on the queue. >> 2. What happens with failed jobs?

Resque provides a great interface for this, an let's me manually requeue the job. >> 3. Is it possible to get a list of queues that a worker is watching? > > Yup, you ask the client. I was hoping to avoid asking the client. Say you have hundreds of workers, querying each of them doesn't seem to make much sense since the server already knows what queues the worker is watching in order to send it jobs. > >> 4.
