Hello.

having about 6 Gb free RAM, trying to execute:

```d
string[] dic;
	
for (int i = 0; i < 100_000_000; i++)
{
	
	dic ~= "just a word number "~to!string(i);

	if (i%1_000_000 == 0)
	{
		writef("processed line %s: %s\n", format("%,3d", i), 
format("%,3d", dic.length));
	}
}

```

got an error:
"processed line 32,000,000: 32,000,001
core.exception.OutOfMemoryError src\core\lifetime.d(126): Memory 
allocation failed"

app used is about 1.6 Gb, more than 4 stays free.

1. What is happened, why dynamic array have mem limit? For 
example, golang uses all free memory that it can.
2. How to fix this?
3. (optional) How to display memory usage? Cannot find function 
for this.

Thanks.

Compiling to 64bit with: `dmd -m64 -run test.d` works no problem

Switch to /bin64 and now works until full memory using.
