I don't care how this is fixed. I just want a fix.

It would be nice if any fix 
can make it into a 2.2.x maint release rather then wait for 2.3. If you also 
think this way then exploiting 2.3 features is not 
reasonable.

Which version should I diff against to make a 
patch?

On the specific points: Why not return -1?
The -1 is  the 
value set that means no status available.
(See sts variable - not sure 
how this works as a class variable!)
This will be the case if you close 
the fd before the
process exits. Windows version seems to return 
None
in cases where the exit code is not available. But I've not
read 
the code to find out details.

A suppose a __get__() would allow 
forwarding of gets to all of the fd's properties. I may be worth copying the 
functions from the fd to the wrapper for speed.

Note: fd.close() 
returns None not zero.

I was hoping whoever designed the API 
could comment on how they though it should work.
