# It is complicated - not my fault. It's Apple implementing changes in launchctl on 10.10, 10.11
# This script restarts Polipo service (as user not root) after connectiong to VPN via Tunnelblick
# The reason for this restart is that when on Public WiFi connections are blocked by LittleSnitch (firewall)
# Polipo goes crazy waiting for all these connections that disappeared in a black hole
# 'Couldn't establish listening socket: Too many open files'
# So it is better to start clean after getting VPN connection and I am too lazy to do that from commandline.
# Some explanations of why all this is necessary

# experimenting and Google did the rest.
