I've just been looking at this, and from what I can see, am I right in
thinking that the IOCP support is *only* for sockets? (I'm not very
familiar with socket programming, so I had a bit of difficulty
following the code). In particular, it can't be used to register
non-socket file objects? From my understanding of the IOCP
documentation on MSDN, this is fundamental - IOCP can only be used on
HANDLE objects that have been opened with the FILE_FLAG_OVERLAPPED
flag, which is not used by "normal" Python IO objects like file
handles and pipes, so it will never be possible to poll these objects
using IOCP.
