 Mark,

 This patch is from ticket #1344, from o_sukhodolsky. I'm hoping you could
 find the time to review these. I'm separating them out from #1344 as that
 ticket is a mess of things that have already been dealt with. If you
 commit any of these, please credit o_sukhodolsky (who is already in
 COPYRIGHT) and add at least "Refs #1344".


 It appears you committed (or last touched) the code to
 libpurple/dnsquery.c. Obviously, the OSCAR code is something you're
 familiar with. I'm throwing libpurple/dnssrv.c your way as well. If you
 don't want this, let me know.

 From a quick reading, I feel like the libpurple/dnsquery.c changes apply
 to a child process. I'm fairly certain it's not safe to call
 purple_debug_* functions there.
