The docs suggest that it's a stream-to-memory object which means that
the data will be read out of the stream and be made available to you for
processing. I'm not sure how (or if) it will buffer this and what the
memory characteristics are. I think they're calling this (and other
objects) `File` because they offer a file like interface.
