This is easy to test. I did the test, but with gethostbyname(), not 
getaddrinfo().

I started a Python loop that did gethostbyname() and printed how much 
time it took. Then in another window I did "sudo killall -HUP lookupd". 
Interestingly enough, this was not noticeable in the timing. This 
probably means that that watchdog that restarts lookupd when it crashes 
reacts pretty fast.

So next I did "sudo killall -STOP lookupd", and indeed: the loop 
immediately stopped running. So did the rest of the machine, a few 
seconds later: apparently calls using lookupd are all over the place 
(probably log messages and such too).
