Notice how a Slice object is generated. Then a PyObject_GetItem() is done. The salient code path is from apply_slice(). A slice object must be constructed and destroyed.
If slice object creation bothers you here, it might be worth using a free list in PySlice_New() instead of creating new slice objects on request.
Creating a slice of something is not necessarily such a costly operation that it dominates creating the slice object, so optimising the slice request itself sounds like a good idea.
You can take a look at how it's done in tupleoject.c if you want to provide a patch. Then, please open a bug tracker ticket and attach the patch there (and post a link to the ticket in this thread).
