Don't read too much from the "dismissal" of issue 8738.  I will be
happy to reopen it if there are ideas on how to improve the situation.
  For example, it may be helpful to document whether the situation
improved in 3.x and whether pickletools.optimize produces more
consistent pickles.  If you change your mind, please leave a note on
the issue.
