The message callback returns two parameters. I think the first one
identifies the applet that send the message and the second one contains
the message that is send.
So if you would add "echo APPLET_DONE" at the end of your load script as
Bob proposed, you could check for this in your callback function:
function temp_function(app,msg) {
if (msg.match(/APPLET_DONE/)) {
property = getPropertyAsString("boundboxInfo");
}
}
(If you don't use the value of 'property' within 'temp_function' don't
forget to define it globally.)
You can see how this works for example here:

Look at the function '_jmolMessageCallback'. I use it to log the
messages, look for some severe errors and display the number of
currently selected atoms.
