ooh, that would be nice.  I imagine it won't be possible to put it in a 
separate library and have it work nicely with the existing Handle 
implementation; you really want it to replace the existing low-level IO for 
Handles.  If you could integrate it with the existing IO manager thread in 
GHC.Conc, then all the better.

In that case I suggest the best option for now is to pull in as much Win32 
support as you need, in a similar way to System.Posix.Internals which has 
the POSIX bits that the base package needs to know about.
