Sending an interrupt to the frontend?

Hello Mathgroup,

This is a question about frozen frontend behavior.

In development stages, one of my frequent mistakes is to send the 
frontend something that takes forever to dynamically update---at least 
that is what I believe what is happening for most of the "freezing" 
occurrences.  For MacOs, this is often signaled by a "Formatting 
Notebook Contents" window.

I wonder if anyone has found a method to send the front end a message to 
stop dynamically updating while in an unresponsive state?  I've various 
versions of kill -s signal  (i.e., signal = INT) from a terminal in 
MacOSx, but never with success.

I suppose that having the front end query the operating system for 
interrupt requests would create a lot of overhead.  However, I wonder if 
a method to force the frontend to make an operating system query with a 
user-specified time interval might be possible?
