First, sorry for the one month late reply, but I missed your message.

What I mean here is we can use DO for inter threads communication in 
order  to execute each AppKit method in the main thread, and not in the 
special Howl thread. A method like performSelectorOnMainThread in Cocoa 
would make that a bit easier.

… I have seen also that Apple has released an implementation for 
mDNSResponder  posix and windows compatible.
