[Idle-dev] Breakpoint is not reached in multithreading application

I try to use IDLE for debugging my multithreading python application.
In my application i have the following class:
class DataMonitor( threading.Thread ):
'''Updates data with regular frequency'''
_update_frequency_in_sec = 0.5
def __init__ ( self, update_funcs, data ):
threading.Thread.__init__( self )
self._update_funcs = update_funcs
self._data = data
self._keep_running = True
'''Start data monitoring'''
print "i'm running"
time.sleep( self._update_frequency_in_sec )
An object of this class is created from the main thread and is stored there.
When i set breakpoints in the code that is executed in the main thread, they
are reached with no problems.
When i set breakpoints in the while loop of the run() method of my thread
class DataMonitor (at the line with print statement), the breakpoint is
never reached. However, the application keeps running and i get a lot of
"i'm running" messages in the python shell of IDLE.
