Support a timeout and buffer

[bdeitte]

node-statsd-client has some goodness in it like timeout and buffer support: https://github.com/msiebuhr/node-statsd-client/blob/master/lib/EphemeralSocket.js

It would be nice to grab whatever we can from that project (and the license and attribution for the changes of course) to use here

Still don't have socket closing in here, but it's pretty much what I was looking for in #5
