Try this:

[code]
import std.stdio;

void destruct(T)(ref T obj) if (is(T == class)) {
    .destroy(obj);

    core.memory.GC.free(cast(void*) &obj);

    // for valid state
    obj = null;
}

void destruct(T)(ref T chunk) pure nothrow  if (!is(T == class)) {
    core.memory.GC.free(chunk);
}

void main() {
    for (int i = 0; i < 1000; i++) {
        ubyte[] chunk = new ubyte[40 * 1024 * 1024];
        destruct(chunk);
        //delete chunk;
    }

    class A {
        ubyte[] _chunk;

        this() {
            this._chunk = new ubyte[40 * 1024 * 1024];
        }

        ~this() {
            writeln("DTor");
            destruct(this._chunk);
        }
    }

    for (int i = 0; i < 1000; i++) {
        writefln("start #%d run", i);
        A a = new A();
        destruct(a);
        //delete chunk;
        writefln("end #%d run", i);
    }
}
[/code]

I see no differences if I compare this and delete, except that "delete" looks
nicer.
But I have not made a detailed test, like you did. Maybe you could did the same
with my "destruct".
