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.
