I don't think "wait 0" by itself does anything useful. Make a stack with 
two buttons. Running the script in the first button will prevent mouseUp 
events in button 2 from being processed.

button 1 script:
on mouseUp
   repeat forever
     wait 0
   end repeat
end mouseUp

button 2 script:
on mouseUp
   put the name of me & cr after msg
end mouseUp

Now hit command-period to exit to the debugger, change the script of 
button 1 to

on mouseUp
   repeat forever
     wait 0 with messages
   end repeat
end mouseUp

and you can click button 2 and see new text in the message box.
