Subject: Re: getting rid of the target stack

Just FYI,
The problem is that the current target stack implementation is serving
two masters:
- a layer/stack of targets - thread on top of raw/remote. This is a
true stack. As with a stack, each has an above and below and can
propogate requests through it. This part of the architecture works.
- the vineer - live, core, file - are all ``targets'' that can be
switched between and mechanisms that allow GDB to fall back to other
layers if one can't provide it.
Some incremental things that have been pointed out in the past include:
- making the targets true objects - eliminate that global state
- tighten/fix the target stack interfaces so that people don't keep
bypassing them (or worse, as in the hw breakpoint stuff avoiding adding
them to the vector).
