Tested and seems to be fixed.  "rndc reconfig" does not remove all 
member zones.  Same with "rndc reload".

The minor logging issue, that when reading a catalog zone, I get 
multiple lines of adding one zone (which varies from time to time) 
still exists, but that's only cosmetic.

I get 17 of those "catz: adding zone" lines, always the same zone 
each time named starts, but it varies which zone is chosen for the 
honor.

Coincidentally the catalog zone has 17 member zones.  It looks like
some variable is getting set once and not reset for the other member 
zones.

Oh, and I don't see any reason to leave this one as "confidential", 
if you want to move it to the newly-opened bug database.

Thanks again, Mark and Michał. :)
