Python Embedding Importing relative modules

That works, but doesnt solve the problem.

ScriptA.py has a module in its directory called 'bar.py'
ScriptB.py has a module in its directory called 'bar.py'

Imagine the 'bar.py' modules dont have the same content, so
they are not equal.

Now when the first bar.py is imported, the second import for
a "import bar" imports the first one, because its already
stored in sys.modules.
