I'm not actually using os.chidir(), I just used it here to create a
clearer example.
Here is the simplest representation of the problem:

The same problem appears if I use the module (as I pointed in the

A better way to do this was http://pastebin.com/m1130d1fe :)

But this means that there is no way to create a safe Singleton in
python, because the classes are also created twice.
This is the problem that I encountered. I created a complex
implementation of a Singleton pattern using metaclasses because I
needed the __init__ method to be called just once and
Here is the situation:
$ ls
test
$ cd test
$ ls
__init__.py data.py
$ cat __init__.py
$ cat data.py
DATA = {}
$ cd ..
$ python
>>> import os
>>> from test.data import DATA
>>> DATA['something'] = 33
>>> os.chdir('test')
>>> from data import DATA as NEW_DATA
>>> DATA
{'something': 33}
>>> NEW_DAT
