Like Martin said, a missing feature.  I'd also quite like the mmap
module to have a C API, but as my use case is especially evil (


) I'm not going to push that hard :)

I'm not entirely sure about this, though.  Does 

mmapinstance.__setitem__(slice(1,2), 'a')

work?  AIUI __setslice__ and __getslice__ are out of favour these days
(not sure though).

Any patch to fix one of these would probably also fix the other almost
as a sside-effect...
