I don't think so.  OverflowError is a subclass of ArithmeticError and
is raised when result of an arithmetic operation cannot be represented
by the python type.   For example,

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: (34, 'Result too large')

I don't think failing pickle dump should raise an ArithmeticError.
