patch3

Unfortunately I had not been able to reproduce any broken piglet tests, which
were mentioned, introduced by this patch (obviously I tested only on my
hardware, but piglet results were equal). Anyway I propose two patches, which
solve this bug. First is not using any floating point arithmetic, just integer
division, which is equal to rounding down and therefore should not allocate
more chunks than available. Second is straightforward obvious fix to the
original code - checking for null before two divisions.
