Please find attached our changes. I am sending you two patches since I
came across possible memory leaks while working on the original patch.
The first patch (perf_python_retval_decref.patch) adds calls to
Py_DECREF for the references returned by PyObject_CallObject().

The second patch (perf_python_add_sample.patch) contains our changes to
hand down the sample information for generic events. In addition, the
call-chain of the samples are constructed into a list and passed on. In
the case of generic events, this is just another entry in the dictionary
that is passed to the script as sole argument. For tracepoint events,
this adds another argument and hence changes the scripting interface.
Please feel free to remove these lines in python_process_tracepoint() if
you think that this is problematic.

I hope it is no problem that I am sending you two patches in one mail.
The patches are based on the git repository you pointed out, last
updated on April 2nd (commit 675b44bdf5f2a245f4479c5a8c40abf591007f36).

Please let me know if you have any questions.
