Do you need the stream outside that method? If not, don't use an
instance variable, and use a local variable instead.

def download
  stream = Stream.find(params[:id])
  ...
end

When the method finishes executing the stream variable goes out of
scope, and it's the only reference to that object, so that memory can
be freed by the GC.

Jesus.
