I hear that malloc is a "relatively" expensive task.
It's mostly just OSX's malloc that is obscenely expensive beyond a certain size. But that threshold is more like 16k or so. On Linux, it's 128k instead, but if both thresholds were the same, you'd see that Linux takes this change well, whereas OSX does not.
The threshold corresponds to when malloc switches from doing its own memory management, to just delegating its job to the kernel.
