Just to prove my point, I will write one which is capable of
doing adaptive memory usage based on decompressed size.

This way, small files could still use however big dictionary size 
one chooses, maximising compression ratio and yet still consume 
much less memory than 8M.

Big files can consumed at most the size of the dictionary.

It will add a few hundred bytes to the binary.
