I'm using pySerial to read from a serial port.
One thread reads from the port, with no timeout.
Another thread handles output and other tasks. This works
fine until I want to shut down the program. I can't reliably
break the program out of the read when it's waiting. On Windows,
closing the serial port will abort the read, but that seems to have no
effect on Linux.

I know, I could put a timeout on the read and handle all those
null returns. Is there a better way?
