Calling f.tell() right after the first getLines() call shows that it isn't reset back to 0. Is this correct or a bug?This is expected. Part of the iterator protocol is that once an iterator raises StopIteration, it should continue to raise StopIteration on subsequent next() calls.
Is there any way to just create a new generator that clears its `closed` status?
