Why not sys.modules['sys'] = mydic instead of trying to rebind
sys.__dict__?   You can't affect those other modules which have ALREADY
imported sys, yourself included (but as for you, you can remedy that
easily -- sys = sys.modules['sys'] = mydic...), but otherwise you should
be OK.  sys.__dict__.update(mydic) as the last statement might also be
an alternative (and if it works for your purposes, it's cleaner than
rebinding sys.modules['sys']!-).
