I'm looking at MM 2.0.13 so things may be different with the 2.0.6 you are 
running but not by much.

Only one instance of the cron launched qrunner should be extant at any one 
time.

 From a quick look at the code, that instance may spawn child processes 
although the only case I can see is in the ToUsenet handler.

It isn't obvious to me that this will lead to Mailman sending out multiple 
copies of a message. Have you been able to observe Mailman doing this in 
your MTA logs?
