Yes, I also have a local caching nameserver, pointed to by the "nameserver 127.0.0.1" entry in /etc/resolve.conf. Also, it seems that Tor/libevent is smart enough to filter out duplicate DNS servers as 3 copies of "nameserver 127.0.0.1" doesn't give you more retries on the same server.
On a semi-related topic, I can now say the using BIND v9.7 greatly reduces the number of these Tor entries relative to using Unbound v1.4.13. This is true with Tor 0.2.2.34 on the low (Intel Atom) and high (Xeon 56xx) ends of the CPU spectrum.
I am running ubound. I increased the num-threads parameter in ubound.conf but that did not to help. Than I stopped unbound and installed BIND 9.7.3 but I don't see any difference.
