[PEAK] Infinite loop in events.subscribe()

[John Landahl]

(sent from wrong address previously; ignore duplicate message, if any)

Just tried events.subscribe() for the first time today, and it seems to 
generate an infinite loop when the event source fires.  Attached is the 
traceback from something like:

      condition.set(True)

where 'condition' is an instance of events.Condition to which some other 
component has subscribed via events.subscribe().
