> By having getAvailableRows() and prepare() separate, any implementation is forced to perform 2 queries. Many systems allow getting the results of a query and the total count in one query so that you don't have to perform 2 queries. Getting around this requires some pretty gross hacks (unless you just don't use grid at all which is unfortunate).
