Yep, that's it. Still not sure where the delay comes from, though.

With tcpdump I see that most requests are immediately answered with "no
such domain". The only exception are AFSDB? requests for top-level
domains -- those seem to take up to four seconds:

   10:45:43.637524 IP localhost.58442 > localhost.domain: 57292+ [1au]
AFSDB? git. (32)
   10:45:47.131635 IP localhost.domain > localhost.58442: 57292
NXDomain* 0/0/1 (32)

Multiply that with retries and other VCS and the whole delay blows up to
a minute.
