1) If using the GC, but for whatever reason, I need to free something _right now_, is core.GC.free() the proper way to do this?
The main problem is that `new` does not necessarily give you a pointer to the start of an allocation, and `GC.free()` does not work if you give it a pointer to the interior of an allocated block.
You could use `GC.addrOf()` to get the base address from an interior pointer, but I don't know whether there could be other objects/arrays sharing the same memory block.
If you explicitly allocated the memory block yourself with `GC.malloc()` then you have full control over what is placed in it and can safely `GC.free()` the memory using the base address.
Keep in mind, `GC.free()` does not call finalisers.
