Almost 3GB available on a 48GB machine is very close to "free memory is
0" and "used memory is close to total", which is why I´m wondering what
I can get away with :)
This free memory can go away in less than a second. Maybe it never will,
so I figured why not use as much as possible --- just not too much, and
this is borderline.
