Micro-threads: a simple example, UDPPort wrapper

[Mike Fletcher]

Attach to find a fairly simple UDP port wrapper which uses three
micro-threads to perform polling of a basic socket.  As you can see, without
select support, this is inefficient (it is constantly checking to see if it
can read/write).  More on that in a follow-up :) .

Enjoy,
Mike
