I had the two nodes send updates bidirectionally, so that each could
serve as a master.  This is a normal path for replication, first there
is one node, then master/slave is made and finally master/master mode
is introduced.  I saw a possibility to do this with NSD.

I've not actually fed it with information from various sources though.
One of the nodes was in practice always the first one to process new
zone versions.  The only thing that probably was added is an update
sent back from the slave to the master, which I expected to be ignored.

To my surprise though, I've experienced difficulties stopping and
restarting NSD.  As Casper Gielen reported, the problem may also be
related to something else.

This is not a bug report -- merely sharing experiences.
