The amount of code is not what i mean. It's the organization that lacks
coherency. There's too many things tacked on half-heartedly knowing whether
that was the right thing to do or the right place to put it. So any patches
i submit could easily break something on some other system, and it's hard to
know.

I'll cut or re-arrange various steps i've seen (during "run"), but i won't
submit any patches for months (needs a lot of checking).

I was going to copy stuff starting from scratch, but that seems a bit of
effort after trying it. I'll just evolve the current gdb a bit.
