my idea at first was to add a breakpoint at function entry with a 
command that enables "catch throw" and another breakpoint at function 
exit that disables.  then i thought about things such as recursion and 
multiple threads, and how the heck do you set a breakpoint at function 
exit, and wrote the brute force stack lookup instead :)
