Thanks, Gary. That seems to work. The call stacks seem to be inverted  
(or maybe I'm reading them wrong), but the symbol names are there and  
this will definitely be useful. When I get enough time to put in  
serious optimization work, maybe I can take a look into the dSYM  
approach.

Thanks,
Thom
