Program now terminates when the interface is removed
Increases the number of os threads (relevant for Go <1.5, not tested)
More consistent commenting
Improved logging (additional peer information)

I am not entirely convinced the use of net.IP is a good idea,
since the internal representation of net.IP is a byte slice
and all constructor functions in "net" return 16 byte slices
(padded for IPv4), while the use in this project uses 4 byte slices.
Which may be confusing.
