"""
list.sort is interesting in that it calls a C function, that calls back to a
Python function. In an ideal world, we'd be able to record the time inside the
Python function _inside_ list.sort, but it's not possible currently, due to
the way that Python records frame objects.
Perhaps one day we could add some functionality to pyinstrument_cext to keep
a parallel stack containing both C and Python frames. But for now, this is
fine.
