druntime should define a proper, authoritative, place to calculate that 
page size, and then use the page calculated here.

I did some tests today, and it require quite a lot of changes. But it is 
mandatory to run D on any system where the page size isn't 4Kb.

So first question, where this should be calculated ? In core.memory ?

I do have a patch for that, but I have no clue where GetSystemInfo is 
defined (grep didn't helped me much here) so it will not work on windows.

Additionnaly, I don't have a windows machine.

being used at all...
