It is a well known problem, with no easy solution. Proposals welcome. 
Perhaps we should start a new thread and I can lay out some of the 
technical difficulties?

It's possible, if done carefully, but of limited benefit, as Bucardo 
needs active, serializable, concurrent transactions most of the time. 
You may get more benefit by having the KID and CTL processes exit 
when done, by setting kidsalive=0 and stayalive=0 for each sync.
