[Pythonmac-SIG] Non blocking terminal input

[Samuel M. Smith]

Is there an equivalent on mac/unix to the msvcrt module for windows 
kbhit() function?
Or in other words is there some way to do non blocking reads of the 
terminal as opposed to blocking reads vis a vis raw_input()?
In other can I non blocking poll the terminal input to see if something 
is there before I read it.

It looks like I might be able to do it with curses.getch() with  
nodelay(True)

Can I treat the terminal stdin as a file and use ftell to see if more 
characters have been added since
the last check of ftell?

I am playing around with generator based weightless threads and wanted 
to see if I could do interactive I/O with the terminal while running 
other tasks.

I know I could do it with threads
