> kvbuffer.length = 2146435072 (2047 MB)
> Corner case: bufIndex=2026133899, kvbidx=523629312.
> distkvi = mod - i + j = 2146435072 - 2026133899 + 523629312 = 643930485
> newPos = (2026133899 + (max(.., min(643930485/2, 271128624))) (This would
> overflow)
> {noformat}
> Would be good to restrict the max allowed sort buffer to 1800 instead of
> 2047.
