Automatic reload()?

That could cause some confusing problems if you're unlucky about the
order the modules get loaded in.  E.g.:

A.py:
######################################################################
import B, C
reload (B)
reload (C)

t = B.B ()

B.py:
######################################################################
import C

class B (C.C):

    def __init__ (self):
        C.C.__init__ (self)
        
C.py:
######################################################################
class C:

    def __init__ (self):
        pass
    
% python A.py 
Traceback (innermost last):
  File "A.py", line 5, in ?
    t = B.B ()
  File "B.py", line 6, in __init__
    C.C.__init__ (self)
TypeError: unbound method must be called with class instance 1st argument

The problem is, the C.C which B becomes a subclass of is the version
from before the reload, but the C.C in C.C.__init__ refers to the
version following the reload.
