Sounds like tarfile needs a seekable file. How big is this file you're
reading? Can you simply read the whole thing into memory, then use
io.BytesIO? I had a quick glance at help(BytesIO) but didn't find a
simple way to make a buffer that reads from an upstream file when it
needs more content, but it should be possible to build one.
