A method and system for managing parallel resource requests in a portable computing device (“PCD”) are described. The system and method includes generating a first request from a first client, the first request issued in the context of a first execution thread. The first request may be forwarded to a resource. The resource may acknowledge the first request and initiate asynchronous processing. The resource may process the first request while allowing the first client to continue processing in the first execution thread. The resource may signal completion of the processing of the first request and may receive a second request. The second request causes completion of the processing of the first request. The completion of the processing of the first request may include updating a local representation of the resource to a new state and invoking any registered callbacks. The resource may become available to service the second request, and may process the second request.
