I am attempting to read a character at a time from stdin using getch.
Unfortunately, it buffers my input until enter is pressed.  I tried
unbuffering stdin using something like:

		setvbuf(stdin,NULL,_IONBF,0);

but it doesn't seem to help.  I don't want to use the conio functions
because the input is going to be redirected using ctty.  Does anybody
have a fix?  Does anybody know what I am talking about?  Does anybody
care?  Does anybody really know what time it is?
