As stated in the text you top-posted, if you had read it, I specified
a host+domain name in torrc. That host+domain name combination is updated
at dyndns.org upon system startup and within ten minutes of any change.
I use inadyn to test and update the dyndns.org name server data base.

I run FreeBSD 6-STABLE. There is no entry in /etc/hosts because
/etc/nsswitch.conf is set to have the resolver routines check /etc/hosts
before querying name servers. An entry in /etc/hosts for the chosen
host+domain name combination at dyndns.org would defeat the purpose of
using inadyn and the dyndns.org service. Although I have not spent time
to familiarize myself with the tor source code, especially since I have
yet to encounter written documentation of its internal structure, I am
not an idiot. I have also been doing UNIX system administration for two
decades.

nslookup is a pain in the butt. I normally use dig. In any case,
as stated in the text that you ignored, the IP address had not changed.
Therefore it had not been altered at dyndns.org. And, yes, I did check.
The address had not changed at dyndns.org, and it had not changed here.
The ADSL modem+router's log showed only the initial PPPoE exchange that
resulted from plugging it in. If the IP address had changed, all of that
would have had to appear in the modem+router's log.
tor has now been up and running for just over five hours since I
stopped and restarted it because of the problem. There has been no
recurrence during this time.
