I've done a threaded fix already.  You're welcome to have a go at doing it
without a thread if you want, but I think it'll be messy.

Looks like, yes. Mixing the high-level buffered file I/O together with select() (and non-blocking fd's) usually doesn't work out very well. Going down using os.read() instead likely makes the code more complex than using one thread per file descriptor ...

cheers,

  Gerd
