On some of my smoker systems:

#   Failed test 'setting redis_write to a different value than redis_read and calling it will work.'
#   at t/01_init.t line 28.
# died: RedisDB::Error::DISCONNECTED (Couldn't connect to the redis server at 127.0.0.1:6379: Connection refused)
Couldn't connect to the redis server at localhost:6379: Connection refused# Tests were run but no plan was declared and done_testing() was not seen.
# Looks like your test exited with 111 just after 6.
t/01_init.t ............
