It does look like is sort of a bug,

Though in all honesty I wouldn't be using oslo.service or that looping

https://pypi.python.org/pypi/tenacity is a much better library with more 
`natural` syntax and works more as one would expect (even under threaded 

If I could of I would of never let 'loopingcall.py' become a file that 
exists, but the past is the past, ha.
