I'm not completely sure, but it's difficult to prove that i _don't_ need `-w 2` so I'll add it back in. 

FYI sending sprout SIGSTOP seems to hang the SIP handling, but does not prevent the TCP connection being established:
```
[sprout]ubuntu@ec2-54-81-138-198:~$ sudo kill -STOP 10609
[sprout]ubuntu@ec2-54-81-138-198:~$ time /usr/share/clearwater/bin/poll_sprout.sh
SIP poll failed to 10.154.153.52:5054
Connection to 10.154.153.52 5054 port [tcp/*] succeeded!

real	0m6.139s
user	0m0.032s
sys	0m0.040s
