import hooks (custom module loaders) for pypy do not work
<p>I'm successfully able to create import hooks to load files directly from memory in python2.7.  The example I used was the accepted response to this question:</p>

<p><a href="https://stackoverflow.com/questions/14191900/pythonimport-module-from-memory">python:Import module from memory</a></p>

<p>However; when applying this code on pypy; i get an import error.  I have also tried other import hook examples that work with regular python but not with pypy, such as this:</p>

<p>Does anyone know why import hooks do not work in pypy?  Is there something I am missing?</p>
