As I understand, the test is as follows:

import core.memory, core.stdc.stdio;
void main()
{
    void*[100] arrays;

    // allocate and free lots of 10MB arrays
    foreach (ref x; arrays)
    {
        x = GC.calloc(10_000_000, 1);
    }

    foreach (ref x; arrays)
    {
        GC.free(x);
        x = null;
    }

    puts("must have a small working set here");
    getchar();
}

(didn't test)
i.e. the working set never shrinks, so your best strategy is not let it ever
grow.
