Ahhh!! I just found a gremlin bug that only sometimes rears it's ugly
head. Killed it. But now I have to release 0.32. To be released later
today. Please hold off on 0.31.

The bug had to do with not checking for an established connection with
netstat. So I was sometimes getting a duplicate entry when the state
of the socket was something other than established. Fixed by modifying
this line

netstat -t -e -n | grep :6000 | sed -e 's/:/ /g' | awk '{print $9,$6}'
| sort | uniq

to

netstat -t -e -n | grep :6000 | grep -w ESTABLISHED | sed -e 's/:/ /g'
| awk '{print $9,$6}' | sort | uniq
