> Non-blocking redelivery does not calculate exponential delivery properly when
> retries of delivery are interspersed with (successful) deliveries of other
> mes sages.
> This is caused by the fact that last redelivery delay is stored in a field
> and is overwritten delivery of other messages. A possible fix is that
> redelivery delay can be calculated each time by simply doing multiplications
> in a loop (as it is done in broker) or using mathematical exponent function.
> At the same time redelivery count can not be a single field but an array with
> a counter per each message waiting for client side non-blocking redelivery.
> I can provide a patch for this and a unit tests.
