I'm looking for the same sort of thing. I want to setup a queue specifically for enqueuing a lot of work (40K items). The per-item processing is variable from a few seconds to many minutes. I'd like to know when they are completed to proceed to the next stage of processing.
In my case, there would not be any expected new items to arrive at this processing stage so I would use a low-timeout. (but waiting a minute wouldn't be problem.. so the perf on the "is empty" is not a large concern in this case)
