reclaim memory to os which allocated with new

[ota]

Hi

A lot of try and finally i found that:

When i used __delete(), and GC.minimize() which reclaims memory 
to os and while checked with gnome system monitor; i see that all 
memory is reclaimed.

For example:

     `
         import std.stdio;
         import core.thread;
         import core.memory;

         void main() {
         	int[] ints = new int[500_000_000]; // about 2 GB
         	writeln("allocated...");
         	for (int j = 0; j < 500_000_000; ++j) {
         		ints[j] = j;
         	}
         	writeln("assigned...");
         	Thread.sleep(5.seconds);
         	writeln("now 5 seconds sleeped...");

         	__delete(ints); // removing...
         	GC.minimize(); // reclaming

         	writeln("memory is freed...");
         	Thread.sleep(5.seconds);
         	writeln("5 seconds more sleeped...");
         	writeln("finishing...");
         }`

Checkable with monitor tools for whether works or not.

`ints = null`, `GC.free(cast(void *)ints)` didn't work.
Just in case i wrote that for use.

Thanks.
