Starts the job. If the job was run once before, resets it completely. Can

as_thread (bool): Start the job in a separate thread. This is #True by
default. Classes like the #ThreadPool calls this function from its own
thread and passes #False for this argument.
daemon (bool): If a thread is created with *as_thread* set to #True,
defines whether the thread is started as a daemon or not. Defaults to
#False.
