这是一个具体的例子

procedure DoStuff;
var data:TBytes;
begin
  data:=GetData; // lets say data now contains 1 Gig of data.
  DoStuffWithData(data);
  // I now want to free up this 1Gig of memory before continuing.
  // Is this call needed,or would the memory be freed in the next line anyway?
  Finalize(data); 

  data:=GetMoreData; // The first array now has no remaining references
  DoStuffWithData(data);
end

调用Finalize()是多余的吗？
