Automate count in scroller when there's no more data

The count query is the slowest part of my database query when using the scroller.

What I'd like to do is skip the count query (that is,not return a total in the ajax), but have the library continue to make ajax requests until there's no more data.

Obviously, the scrollbar wouldn't be accurate -- it'd look like it was near the end, then as more data is fetched it would adjust. This seems to be common in other infinite scrolling systems.

Perhaps I could simulate this on the server-side -- the first time it makes a request I'd return a number higher than the records_per_page, but then when it requested that I'd change that number, until I run of out data, and then I'll know the actual count. But that way feels pretty messy, so I figured I'd post it here for discussion first, maybe there's already a solution.

    This indeed has come up a couple of times already, but it isn't something that is currently possible I'm afraid. Those paging calculations are fairly embedded into DataTables.
