Running on winxp with IDLE, I get the second traceback, all the same after the first line. Given "target is the callable object to be invoked by the run() method.", I would have expected this to work too.
Problem is not builtins:
class C:
 def f(s): print( 'here')
p = multiprocessing.Process(target=C.f, args=(C(),))
p.start()
gives same error, ending in
_pickle.PicklingError: Can't pickle <function f at 0x00FE5AE0>: it's not found as __main__.f
