[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...
