Add code to Amazon MWS PHP API code for Parallel Requests

Add code, or create new PHP class/script to make Concurrent Calls to the Amazon Seller MWS, probably using curl_multi_init or some kind of rolling curl call like [login to view URL] You should be knowledgeable of the Amazon MWS (Marketplace Web Service) PHP Client Libraries. These calls would be made on behalf of other sellers, so each concurrent connection would be using a different seller/merchant ID but on the same type of call (example multiple sellers making call on this [login to view URL]) thus allowing for concurrency even with throttling. I would like to get certain PHP libraries updated to allow for concurrency. THanks
