This is not a bug. You didn&#39;t *nearly* reset Python to the state in which 
it was before the import: the modules that got imported recursively still hang 
in sys.modules.<br>
<br>
Please accept that Python indeed does not support unloading modules for severe, 
fundamental, insurmountable, technical problems, in 2.x.<br>
<br>
In 3.x, chances are slightly higher. In principle, unloading could be supported 
- but no module actually adds the necessary code, and the necessary code in the 
import machinery isn&#39;t implemented in 3.2 and earlier.<br>

<br>
Supporting unloading will be (and was) a multi-year project. Don&#39;t expect 
any results in the next five years.<br>
