Log rotation - ie, renaming a file - isn't affected by the permissions 
of the log file.  The permissions of the *directory containing the log 
file* control whether it can be renamed (and a new one created) or not.

So it doesn't matter what permissions the log file has.  It only matters 
what permissions you set on the directory holding the log file.  That's 
outside of the control of twistd.
