I think that more than "hard to implement portably", it's just not a 
good idea... it's as good as a GUI application that says "To exit open a 
shell and kill this program (the Close button doesn't work)".
If you kill a thread, how do you know what was it doing? Was it 
malloc()ing something? Was it writing to a file? Was it playing with 
some global variables? Was it holding a mutex?
I'm not an expert in multi-threaded programming, but I think if a 
program really wants to use something like this, it's broken.
