Why? You should just get the callback called twice.
Confirmed.
But that makes notes('pending_dns_queries') (in trunk/plugins/dnsbl) go
negative, revealing a race between receiving the rest of the answers
and
going on to the next plugin.
Got any suggestions on a more resilient way to lock here?
Hmm. I don't know too much about DNS, but can we assume that all the
responses will come back in one packet? If so I guess we can accumulate
the results and do the callback once. Or if we don't want to change the
API I guess we could have a "finished()" callback. Thoughts?
Matt.
