By returning out of memory, unrolling the stack, then at the top level displaying the error.

How? Putting up an alert usually requires allocating memory somewhere, be it 
in your application or in the display server.

If we're already out of memory, the likelihood of another set of allocations 
succeeding is quite low. Not to mention that, by the time you do run out of 
memory, the chances are that the system has been swapping hard for several 
minutes. The user will have likely pressed the Reset button long ago.
