Something ought to be done, I agree.  The problem is that it's not 
really readTextDeviceNonBlocking that's the problem, but rather the 
Win32 implementation of FD (GHC.IO.Handle.FD), which doesn't support 
non-blocking operations.  I really hope someone will make a better Win32 
backend for the IO library sometime.

I'll add something to the docs for the user-facing API here 
(hGetBufNonBlocking).

Cheers,
	Simon
