Don't you think that getting a one-character from console is something 
that many people do very often? Do you think that all these platform 
independent code should be moved to the interpreter level instead (and 
raises the appropriate error when the platform somehow cannot do 
unbuffered input)? So python developer could do something like this:

raw_input(bufferring = 0)
