I suspect that Finder uses the LaunchApplication toolbox trap to ask 
the Process Manager to both launch the app and send the initial Apple 
event (odoc in this case).  One of the parameters to 
LaunchApplication is--in essence--the Apple event which is to be sent 
first (there's some coercion magic hidden in there).

It's possible that newer Finders use some other technique, of course.
