Code review comment for lp:~nuclearbob/utah/cobbler-pidlock

I updated the check to look for "utah" or "run_test_cobbler.py" on the command line. I'm testing now. The thing about changing the name of the field is that it still could be "available" which isn't a pid. What's a good name that indicates it can either be a state or a pid? Or can we change available to some number that will never be a pid, like -1?
