[Stackless] Segfault on KeyboardInterrupt

[Jeff Senn]

I notice that you are running a 64 bit build...  and I wonder if a
32 bit build would exhibit the same behavior...   In any case
I doubt very many people are using a Snow Leopard build of 
Stackless yet.

Also a gdb stack dump *might* be more useful than the 
Apple crash reporter.
