Summary: bug in long_mul

Initial Comment:
Here's a strange exception:

>>> class C(long):
    __dynamic__ = 1

>>> c = C(1)
>>> c*1
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
SystemError: ../Objects/longobject.c:186: bad argument
to internal function
>>> 1*c
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
SystemError: ../Objects/longobject.c:186: bad argument
to internal function
>>> 

If I change __dynamic__ to 0, all's well:

>>> class C(long):
    __dynamic__ = 0

>>> c = C(1)
>>> c*1
1L
>>> 1*c
1L
>>>
