CPU preferences doesn't get applied

[Daniel Scholtus]

It hangs on "Waiting for data: ..." after trying to change a CPU preference..

Console dump:
---------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/syspeek/indicator.py", line 272, in apply_preferences
    self.start_suppliers()
  File "/usr/local/lib/python2.7/dist-packages/syspeek/indicator.py", line 84, in start_suppliers
    self.suppliers['cpu'].start()
  File "/usr/lib/python2.7/threading.py", line 489, in start
    raise RuntimeError("threads can only be started once")
RuntimeError: threads can only be started once
---------------------------------------------------------------

Shouldn't self.suppliers['cpu'] be .stop()'ed first?
