I think I have found a small typo-bug in tarfile.py, that seems to
be present in cpython upstream, which makes tarfile compression slower.
The issue can be seen here, in line 415 [1] of tarfile.py:
self.cmp = self.zlib.compressobj(9

Also, I guess this patch solves and is closely related to #1044 which was, at
the time (2007), considered "not a bug".

Do we have any final decision on what's the best approach to solve this? I see
some possibilities:

I guess I got it wrong, it's not part of the POSIX standard, just part of the

entirety of the archive, it's an optimization I needed and I think ccan be
quite handy.

set and it has a "mode" property, tarfile._mode is blindly copied from there.
Otherwise, mode is set using the mode argument in the constructor.
