scandir(fd) must not close the file descriptor, it should be done by the caller. Handling the lifetime of the file descriptor is a difficult problem, it's better to let the user decide how to handle it.

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?
