Hi.  fwiw, I've read the patch and past emails.  fwiw, I love the idea but
wonder if it should be done differently.  Adding a new stratum feels
wrong to me too.  But maybe I'm missing something so let me first ask
a question.  Basically all you need is a way to run some special code
when a particular breakpoint is hit, right?  [There's some housekeeping
like needing to intercept program loads (IIRC), but basically the high
order bit is running special code when a particular breakpoint is hit,
right?]  I'm just wondering if this can be done differently without being
as invasive on GDB's innards.  My off-the-cuff thought is to see if this
is something that could be handled from Python.
