Unbuffered keyboard input

[apighin at my-deja.com]

Searching through the archives, it looks like I can't do this.  I guess
I will have to look at Curses.

To tell the truth, what I am really trying to do is to parse a file
that is ever expanding.  The file will be open()ed, parsed, but will
continue to grow in the background.  I can not seem to get Python to
see that the file have changed and begin processing again.  Ideas?
