>>> import platform

('64bit', '')
>>> from cPickle import Pickler
>>> class rec:
...   child = None
...   def __init__(self, counter):
...     if counter > 0:
...       self.child = rec(counter-1)
... 
>>> import sys
>>> sys.setrecursionlimit(10000)
>>> mychain = rec(2600)
>>> from cStringIO import StringIO
>>> stream = StringIO()
>>> p = Pickler(stream, 1)
>>> res = p.dump(mychain)
