Yea, that's the perfect solution. It uses exactly the amount of 
memory that is required and still I'm using D things only.
The only difference is that I need only one variable outside of 
the loop, but it's well worth it because I only need one large 
buffer at a time.
Also refreshed my knowledge about assumeSafeAppend() which is now 
clear to me, thanks to You.

Using this information I'll be able to do a BigArray class that 
will hold large amount of data without worrying that the program 
uses 3x more memory than needed :D

Thanks for everyone,
Such a helping community you have here!
