I definitely think we should implement something similar.   It would help a great deal with some porting efforts.

In some cases on Mac OS X I have observed that exceptions which are not fatal on Mac sometimes ARE fatal on GNUstep.   I believe we should change the logic which deals with exceptions to add a "continue" button and only show the panel when the application is running in debug mode.   This would allow the application to continue when recovery is possible.

Does anyone have any thoughts on this?

The OS X behaviour appears to be for each runloop iteration to be wrapped in a @try{} block with the exception being NSLog'd if it occurs during the runloop.  This is quite convenient for debugging, since you can just read the log and find out where the exception happened, without having to

Yes, I've found it useful for debugging, particularly when you've just implemented a bunch of things.  Just logging the exception allows you to see how the app operates in general, even it the behavior is off.
