Yeah, makes sense - I thought of doing something alike, but my wild guess
was that it's how sysconf() does this. And I omitted premature optimization.

But I like your one-function simplicity.. will send v2 with that :)
Possibly moving __page_size somewhere in .c files - otherwise, we'll end up
with a static variable per-object /ö\
