The alternative to returning a stream iterator is to use "response.write"
(or to return the file content as a string which takes quite a bit of RAM
for large files). If the response length is sufficiently high,
then "response.write" will work with an intermediate temporary file.
This temporary file can be optimized out when you return a stream iterator.
