This affects more use cases than just is_tarfile() and getmembers() results.

is_tarfile() calls open() which is the root cause of the issue. Calling open() 2+ times will also cause the same issue.

In addition to getmembers(), extracting the tar will also silently fail. (and possibly other operations).

I've suggested a different fix in the comment on the PR:
