It sounds like you want an NSOperationQueue, which would map to your
problem on a high level.
http://developer.apple.com/documentation/Cocoa/Reference/NSOperationQueue_class/Reference/Reference.html
I don't know Win32, but PostMessage() sounds a lot like
NSNotificationCenter's postNotificationName:object:. You could do
this to roll your own process list-thing using this and posting
messages to your main NSRunLoop asynchronously, but you'd probably end
up with something that looks a lot like NSOperationQueue.

Hello, all ...
If a certain flag is set, my app needs to advance to the next item
in a list to process it when the previous item is done. However, I
want the user to still be able to stop it, so I don't want to hang
the UI. In effect, if this flag is set, I want the app to act as if
the user had manually selected the next item to process.
In Win32, one way I could do this is by using PostMessage() -- when
the current item is finished processing, it would post a message to
the relevant threads' message queue and it would get processed, just
as if the message was put there as a result of a GUI action. How do
I do this in Cocoa, or is there a better way?
