    Fork/exec a copy of 'gdb', attach it to your process, and execute the 
appropriate commands to dump the stack of every thread. You could, 
alternatively, use the same method 'gdb' uses. I believe it attaches to a 
library that tells it how to understand the threads layout of the processes 
it accahes to.
