If you mean, in main() instead of doing:
while True:
 q.put(["data1", "data2"])
 t = Process(target=popJobs, args=(q, ))
 t.start()
 t.join()
and doing:
while True:
 q.put(["data1", "data2"])
 popJobs(q)
instead. Then, the bug does indeed occur the same way. It did take more
iterations before it occured however. 
If however, you meant:
while True:
 fail=failureObject()
 for x in ["data1", "data2"]:
 checkAlive(fail, x)
 print(fail.status())
Then the bug never occurs.
