Even if umask *does not* allow it (my umask is always 0022 and the
files
ended up being group-writable).
Are you sure?
Perhaps it only happens when running tar as root, although the
documentation doesn't mention this.
And I don't know what other versions of tar do, the safest option is to
have safe permissions in the tarball (it should be fairly easy to change
sage-sdist to do that).
