[issue13591] import_module potentially imports a module twice

New submission from Ryan Twitchell : Use of importlib's import_module function with modules belonging to a library can cause some modules to be imported twice, if such a module is referenced from sibling modules, and from __init__ in the package. I suspect this is a bug, or at best a nuance of p

[issue13505] Bytes objects pickled in 3.x with protocol <=2 are unpickled incorrectly in 2.x
