Except that get_osfhandle and setmode are both standard methods
for doing things in Windows. They weren't invented for cygwin.
setmode, in particular, is actually implemented on some other systems, I
believe. It's probably a no-op but...
It's possible that your fcntl method actually is implemented that way
in Microsoft-land. Have you checked msdn? If so, we should definitely
implement it.
Actually, I have no problems with implementing this in general but I
just want to make sure that we use an existing interface if one exists.
