[The correct fix for this is to add a "step range" packet, which will
speed up the process immensely.  As it happens, I hope to do that for
the next version of GDB after 6.5.]

Breakpoint 1, main () at loop.c:3
3         int a = 200000;
(gdb) s
4         for (; a; --a);
(gdb) n

Program received signal SIGINT, Interrupt.
0x000000000040043c in main () at loop.c:4
4         for (; a; --a);

CTRL-C works for me...
