I spent a while playing with this last night, to no particular
resolution. A few observations:
1) It would be nice to find out what lookupd is up to during the loop.
I couldn't find out how to get it to tell me (for one thing, the
lookupd(8) manpage seems to be very out of date wrt. locating
config info).
2) One obvious difference between the slow Python program and the fast
C program is that Python has calls to bind() in between the calls
to getaddrinfo()... maybe this (or something else) causes lookupd
to toss its cache for some reason?
3) We're not the first to bump into this:

http://mailman.mit.edu/pipermail/krb5-bugs/2003-March/000708.html
That bug doesn't seem to resolved beyond "blame Apple" (hmm,
familiar :-).
I don't think there's much we can do about this, unless there's a
NetInfo wizard in the house.
Cheers,
M.
