_winapi does have some undocumented support for IOCP (used only by 
multiprocessing), but the APIs are not very nice and should not be 
considered stable.

(Also _winapi.ReadFile(), _winapi.WriteFile() only support pipes or 
sockets, not disk-based files where you also have to control file-position.)
