> A MemoryManager#computeMemorySize(double fraction) is needed to calculate
> managed memory bytes from a fraction.
> It can be helpful for operators to get the memory size it can reserve and for
> further #reserveMemory. (Similar to #computeNumberOfPages).
> Here are two cases that may need this method in near future:
