+Added DeprecationWarning when accessing the tarfile attribute of TarInfo
+objects. The attribute is never used internally and is only attached to
+TarInfos when the tarfile is opened in write-mode, not read-mode. The
+attribute creates an unnecessary reference cycle which may cause
+corruption when not closing the handle after writing a tarfile.
