RE: "thread", "thread apply" and "step" ?
Thanks Daniel: I tried my experiments using GDB 6.8 and it does handle
the thread/step combinations sensibly. To be specific, both:
thread apply X step
stepped thread X, even though the previous breakpoint-hit was in a
different thread than X.

Could you try 6.8, or even better a CVS snapshot, and see if it still
does this? That release is several years old.
I think GDB does step the correct thread nowadays.

If you implement vCont, the serial protocol should work just as well.
