I want to make a generator that will return lines from the tail of

raise StopIteration
I know the problem lies with the StopIteration, but I'm not sure how to
tell the caller that there are no more lines for now.

That was actually the behavior I was trying to avoid. If there is no
data to be read, the call will hang. That function is actually called
by a webserver (from wsgiref) so it cannot hang indefinitely.
