   Pretty normal situations that manipulate with sys.path. One can easily
imports a module two times:

>>> import sys, os, decimal
>>> decimal.__file__
'/usr/lib/python2.5/decimal.pyc'
>>> os.chdir('/usr/lib/python2.5')
>>> sys.path.insert(0, '.')
>>> del sys.modules['decimal']
>>> import decimal as decimal2
>>> decimal2.__file__
'./decimal.pyc'
>>> decimal.Decimal is decimal2.Decimal
False
