Simple TCP proxy

[Morten W. Petersen]

OK, I'll have a look at using something else than _threading.

I quickly saw a couple of points where code could be optimized for speed,
the loop that transfers data back and forth also has low throughput, but
first priority was getting it working and seeing that it is fairly stable.

Regards,

Morten
