That's correct: we have an idea and a PoC, no design to discuss or
anything close to a proposal, at this point.

My idea was to ask for obvious problems precluding or complicating this
approach.

I've found a few minor things; so far, nothing unfixable, and no
significant effects on performance, but the fixes will have to become
part of the design and discussion.  I don't think anyone is actually
running the code (and that's perfectly okay), but if that is incorrect,
please let me know so we don't rediscover bugs that I've already fixed.

I think rr (time-travel/reverse debugging with acceptable performance)
support is important, but I think I'm the only one? It seems to be
really slow on this branch, though I don't know how fast it is on
scratch/igc.
