You have a userland application causing the whole OS to freeze?
That'd be a great contribution to <rdar://4578834>. Wait - how do
you "kill Xcode" when everything is frozen?
Matt, what type of bug did you find in your code that was causing
EXC_BAD_ACCESS ?
EXC_BAD_ACCESS is a very general error (memory space violation),
there are millions of possible reasons.

It's your app, so it's under your control.
Suppose you have an app named Fob. Fob links to a third party library
called FooLib. In FooLib contains a function, FooA, that you must
use. Inside of FooA your app is receiving EXC_BAD_ACCESS exceptions
periodically, because FooA is accessing non-allocated or already
disposed memory. You don't have the source for FooLib, and the
developer of it hasn't fixed FooA.
Would the above scenario be classified as TOTALLY under the developer
of Fobs control?

Also: In Xcode, when this happens, I fall into the debugger
window. I would
prefer instead to have the app crash so that I can see what the
end user
would see. How can I arrange for that?
There's a preference for wether you fall into the debugger, but you
really, really want to fix this regardless of this preference's
setting.
