-performSelectorInMainThread: certainly predates Leopard…? I distinctly
remember using it back in the 10.2/10.3 days.

However my problem now is that with all three marked as (oneway void)

message #3 depends on message #2 before it can start, yet msg #3 is done
before msg #2 can finish. I've also seen once where they arrived out of
order.
// from the client
[server sendMsg1];
[server sendMsg2];
[server sendMsg3];
Is there another way to call asynchronously, yet guarantee that the
messages
arrive in order? Or someway to call w/o the GUI blocking for a server
message return?
You can use :
- NSConnection/NSPorts (
http://developer.apple.com/documentation/Cocoa/Conceptual/Multithreading/articles/SocketComm.html#//apple_ref/doc/uid/TP40001479
)
- YAMessageQueue (10.4-): http://www.2pi.dk/tech/cocoa/message_queue.html
- NSOperation/NSOperationQueue (10.5+) :
- [NSObject performSelector:onThread]/[NSObject
performSelectorInMainThread:] (10.5+);
