We did this with Mac OS X for a while (the way Mach Exceptions work  
it's a little easier to implement, you don't need a special library or  
anything like that).  It's pretty neat.  We were doing it  
automatically with all processes on the system, which is even handier,  
but you do have to be careful - if you are attaching with gdb rather  
than dumping core
