Is it possible to get all the objects referencing a given object in Python?
<p>I have a certain object <code>obj</code>
What I want is to get all the other objects referencing it. I know that I can get a reference count as <code>sys.getrefcount(obj)</code>, but that's not of much use in my case - I need the actual referencing objects, although I'm not sure that's even possible in Python...</p>

<p>Also, getting the line of code that created the object isn't of much use to me either - I know, where the object was created - I just don't know who is referencing it at the moment.</p>

<p>P.S. I need this to debug a leak.</p>
