no... obviously i'm using the same patches you are, and most of my  
clients are as well, and the only times i've ever seen qmail re- 
deliver a message like this have been caused by the filesystem  
containing the queue becoming full or developing hardware issues, or  
a poorly written delivery script called from one of the  
recipients' .qmail files.
