Well I mean in the server I did not use much libdispatch - a "one thread per object" model is used - CGIListener objects (which maintains a open socket for listening) have a couple of threads each running constantly open, implemented as simple -[NSObject performSelectorInBackground:withObject:], and CGIConnection objects that maintains a client session used that too. However libdispatch is used in WebUIKit.
