Actually, we do because we use g_malloc/g_free. The functions exit on
memory allocation failure. I'm not sure the same is true of the new
operator... doesn't it throw an exception on allocation failure (that's
what I vaguely remember)?
Also, this is not running in the context of qemu-ga, so I think it is
better to be more conservative and trap memory allocation failure.
