Suppose you have the following modules:

-foo.py::

   from bar import bar_var
   foo_var = 1

-bar.py::

   from foo import foo_var
   bar_var = 2

The problem is that the interpreter will perform the following steps:

-* main imports foo
-* Empty globals for foo are created
-* foo is compiled and starts executing
-* foo imports bar
-* Empty globals for bar are created
-* bar is compiled and starts executing
-* bar imports foo (which is a no-op since there already is a module named foo)
-* bar.foo_var = foo.foo_var

The last step fails, because Python isn't done with interpreting ``foo`` yet and
the global symbol dictionary for ``foo`` is still empty.
