I suggest the ABCs for stream objects should be incorporated into the 
PEP for the new IO library, using this PEP as a prerequisite. The reason 
for this is that the stream ABCs will naturally follow the same class 
decomposition and methods as are defined by the new library (i.e. input 
stream, output stream, and so on.)
