'''
Enables this scheduler to "consume" (i.e. execute)
jobs. Currently, this method must be called only **ONCE** for any
given queue, as it will launch a thread that actually executes the
jobs. The caller is in charge of ensuring this concurrency
limitation; it is therefore recommended that `pscheduler` be used
with a process manager (such as `supervisor
<http://cr.yp.to/daemontools.html>`_) in conjunction with the
configuration `scheduler.combined` set to `false`.
:param daemon:
Specifies whether or not the thread created for the consumer
will be set to a daemon thread, i.e. if True (the default), it
will stop as soon as the main and all non-daemon threads have
stopped.
