Analyzing Python GC output - what is a "cell", and what information is available about it.

[John Nagle]

I'm printing out each entry in "gc.garbage" after a garbage collection in
DEBUG_LEAK mode, and I'm seeing many entries like

<cell at 0x00F7C170: function object at 0x00FDD6B0>

That's the output of "repr".   Are "cell" objects created only from
external C libraries, or can regular Python code generate them?  Is there
any way to find out what the 'function object' is from within Python?

(I'm looking for a possible memory leak, obviously.)
