That's actually how Cocoa used to work. I can't recall whether an alert panel
popped up or if it was just silent. The behavior changed to crashing sometime
in the past, um, 8 years or so.

There used to be either a callback or an overridable NSApplication method to
handle an uncaught exception, but looking at current headers I can't find what
I'm looking for; maybe it's been gone for a long time and removed?
