This is an open issue still: when is the file descriptor closed.

I think the generator returned from scandir needs to support a
.close method that guarantees to close the file descriptor.
AFAICT, the pure-Python prototype of scandir already does, but
it should be specified in the PEP.

While we are at it: is it intended that the generator will also
support the other generator methods, in particular .send and
.throw?
