Cleaning/Releasing large arrays from memory

[rikki cattermole via Digitalmars-d-learn]

Stuff the GC.
You don't need it to care about collecting (or destroying for that matter).

Tell it to free[0] the array directly.

```D
T[] array;

GC.free(array.ptr);
```

Normally I would suggest to create your own buffer, but because of the 
DB library probably doesn't support that, no point trying to force it.
