Awesome.  I've just pushed out a patch to raindrops.git to have
linux-tcp-listener-stats warn if it detects a listener on
0.0.0.0:#{port} but was passed an address of 127.X.Y.Z:#{port}.

Hopefully it's less confusing for future users.

I didn't want to make (currently) invalid addresses raise an exception,
since sometimes I run the script before starting the server or leave
it running when I shut the server down.

Yup, the counts look correct to each address.  I was tired last
night :x
