number of zoneserver instances?

[Bill Johnstone]

Hello all.

I'm running MaraDNS 1.2.12.06 on OpenBSD 4.2 (release) from the ports
system.  I'm only using it as a caching/recursive server, no
authoritative functionality (yet, anyway).

I've tried to setup zoneserver just on the off-chance that one of the
machines making DNS queries against MaraDNS makes a TCP query.

The relevant lines from mararc are:

ipv4_bind_addresses = "127.0.0.1, 192.168.100.1"
chroot_dir = "/etc/maradns"
recursive_acl = "127.0.0.1, 192.168.100.0/24"
tcp_convert_acl = "127.0.0.1, 192.168.100.0/24"
tcp_convert_server = "127.0.0.1"

So there's one instance of maradns itself that binds to both network
interfaces (loopback and external), but I see three zoneserver
instances.  Using netstat and lsof, I can see that zoneserver has bound
to the TCP DNS ports on both the loopback and external interfaces. 
However, I'm not sure why there's a 3rd instance of it.  I just want to
make sure that:

1. My configuration is sane, and
2. The behavior that I'm seeing with 3 instances of zoneserver with my
configuration is exactly to be expected.

Thanks for any assistance.
