[(Delay forDuration: 10 minutes) wait. self myMethod] fork

This forks off a background process, waits 10 minutes, then calls  
myMethod. Note that a lot of code will break when called from a  
background process, you will have to worry about synchronization.  
Especially you must not call UI code from the background (there are of  
course ways to allow that).
