The old code sets ref=0, then just free's the memory.  My method would 
set ref=1, then call Release() which decrements ref and free's memory.

If QueryInterface succeeds, then it will increment the reference count 
again, so we'll only end up free'ing memory in Release if the 
QueryInterface fails.  It's a more COM-ish way of doing things... the 
original code still works though.
