Here is an alternative solution. We can limit the number of processed
requests to fit in a 1Gb memory chunk for each pass. Obviously, we left
some requests in the queue to be processed in the next call. We can
overcome this by using multi-step processing: estimating the number of
steps in the beginning and processing requests again.
I'd like to hear your opinion on the subject.
