Sorry, I made a mistake (forgetting to clear a breakpoint) when I ported
the stub single step code into gdbserver. As far as I can tell, single
stepping works fine now.
BTW, should I be worried about MIPS16 instructions? (single step
breakpoints are always placed on a 4 byte increment) ...or is that a
