Determine whether a message has been received

[JosXa]

From the given options, I'm unable to tell if there is a way for the producer to tell whether his sent message has been picked up by any consumer. Is that supported by this programming model?

[JosXa]

I suppose I'm looking for something like a messageExists or isDeleted method, but can't find anything along those lines.

This is implementation/clone of RSMQ in python, which, as far as I remember, did not have this functionality - but it seems like it should be easy one to implement - it is just checking for an ID in Redis...

If you care to submit a patch, I would happily accept it otherwise I will try to get to this and #4 as soon I get some time :-)
