Ken, I've tested this in our mixed 2.2/2.3 backend environment.  It  
seems to behave correctly for all 2.2 <-> 2.3 xfers.  I'm not running  
any 2.2 frontends, but it's clear to me that the code will function  
correctly in that case as well.  This is a very elegant solution.   
Thank you for it!

Paul recently submitted:

which fixes:

	1) reconstruct removes already expunged messages, defeating delayed  
	2) reconstruct doesn't tell the "sync" service to replicate its changes
	7) reconstruct should notice and correct mailbox ID conflicts

We still have these open issues:

	3) xfer doesn't replicate expunged messages

( ):
	4) xfer onto a replicating backend causes sync_client to exit
	5) xfer off a replicating backend doesn't remove data from the replica
	8) renaming users causes sync_client to exit

And the biggie ( ):

	6) removing folders doesn't benefit from delayed expunge

What will it take to get a workable solution to this problem included  
in production releases?
