I find it easier to run serial communication in a seperate thread if I need
asynchronous communication.  You don't normally have so many serial ports
open at a time that the threading overhead is significant, it is much easier
than messing with the overlapped I/O stuff, and it is platform-independant.
To be entirely honest, though, the couple of Python programs I have written
so far that use the serial port have not bothered with threading either -
they just send out something, and wait for a reply or timeout (using the
inWaiting() function from pyserial, along with time.sleep).  But if I needed
something more advanced, then I *would* use threads - I've done it in
Delphi, and it works fine.
