     * <p>Multiple requests can be in progress at once. They are processed in

     * first-in, first-out order, with minimal delays between each

     * capture. Requests submitted through this method have higher priority than

     * <p>Multiple regular and reprocess requests can be in progress at once. If there are only

     * regular requests or reprocess requests in progress, they are processed in first-in,

     * first-out order. If there are both regular and reprocess requests in progress, regular

     * requests are processed in first-in, first-out order and reprocess requests are processed in

     * first-in, first-out order, respectively. However, the processing order of a regular request

     * and a reprocess request in progress is not specified. In other words, a regular request

     * will always be processed before regular requets that are submitted later. A reprocess request

     * will always be processed before reprocess requests that are submitted later. However, a

     * regular request may not be processed before reprocess requests that are submitted later.<p>

     * <p>Regular and reprocess requests can be mixed together in a single burst. Regular requests

     * will be captured in order and reprocess requests will be processed in order, respectively.
